☘️New Celitc Coach | Wilfried Nancy Attacking Ideas (VIDEO) Some interesting concepts explained; ▪️Ball-oriented overloads → Create strong overloads close to the ball with patient short passes possession to create; - Numerical Advantage + a free player between lines ▪️Space over Position → Players move dynamically within the overload... zone to identify the free space between lines → Same applies for the ball-far players providing diagonality position '' as close position as needed '' → From the diagonal position they can accelerate the attacks or again find the free player between the lines ▪️Manipulate opponent defensive structure → As explained in the video the idea is to attract and move opponent heavy towards the ball as many times as needed until opponent cannot solve the situation fast or properly 📽️ Created with Metrica PlayBase | Metrica Sportsshow more

Racing Santander - In possession analysis Some interesting concepts applied by Racing: 1⃣ Ball-Oriented Overload ▫️Strong ball-oriented structures to create numerical advantage ▫️Quick combinational play to find the free man in short spaces via 3rd man, lay-offs ▫️The overload manipulates opponent structure to shift with many players to one area in order to defend the overload which ➡️ creates either spaces between them or in the ball-far side ➡️ that Racing tries to reach via diagonality positions and passes 2⃣ Diagonality Switches / Minimum Width ▫️The ball-far players always position themselves diagonally to create an open body position to ➡️ accelerate attacks in potential switches away from the ball-oriented overload 3⃣ Re-shape (after ball-loss) via short-passes ▫️Big idea with the overload ideas is to better control the potential transitions against and have stronger counter-pressing ▫️I like the idea of after ball-recovery ➡️ play quick short passes, within short distances to ➡️ control the rhythm + give time to create new ''overload'' situations in a ''controlled'' way 📽️Made with Metrica PlayBase | Metrica Sports

Up, Back and Through Possession 5v2 in the area in which the ball is. 🔵 Target is to get the ball from one end player to another. The ball must go through the central player on the line. The ball will either go into the central player, who will set to the run of one of the two wide players, or he will set back to the other midfielder who will again look for the run of a wide midfielder (Up, Back and Through). Both wingers will be on the outside lines of the half with the ball, when the ball is transferred the central player will move into the new area, one defender will follow into the other half and the two wingers will follow to create the 5v2.

Iran's as their last minute goal vs Egypt was overturned by VAR denying them a crucial victory that would have guaranteed an advancement out of groups. The player was in an offsides position when the ball was played by the original shooter so he cannot play the ball on the rebound. That is if there is a deflection. There is an exception: If a defending player deliberately plays or controls the ball (such as attempting a back-pass or a controlled clearance) and it falls to you, the offside is reset, and you can legally play the ball. That obviously doesn’t happen here. It’s a clear deflection and rebound in this play and isn’t the defense gaining control and sending it to the originally offsides player. It’s the right call by VAR. Same reason a penalty or free kick taker can’t hit the ball first if they hit the post.

You've been watching football wrong your entire life. This 40-minute Databricks talk on how LaLiga uses data is the proof. The goals and assists you obsess over are the least interesting numbers on the pitch. By fusing tracking data (every player's position, many times a second) with eventing data (every action on the ball), LaLiga measures the invisible game space created, defensive lines pulled apart, the value of a run nobody passed to. The best player in a match is often the one who never touched the scoresheet. Pair it with article by Roan and you are good. Once you see the game as data, you can't unsee it.

Speed Option Trick Play - Linemen are instructed to stand straight up, shoulder-to-shoulder, and not move initially. - The fastest player on the team, who must be small, is key to the play. - The play starts with motioning a player across to get the opponent's eyes to look away from where the play is going. - The play includes a halfback running in that same direction. - Player taking the handoff bends over and sticks his hands back between his legs as far as he can. - The ball is placed between number two's legs. - The player holding the ball is told to count "1,001, 1,002" and then yell "go". - The most important block is performed by the left tight end.

For midfielders wanting to enhance their performance, Ngolo Kante should be a primary source of education. (This is also a reference point I use personally as a midfielder). Kante demonstrates himself as one of the greatest anticipators in football in a pivotal moment; he’s caught ahead of the ball. He teaches that you shouldn’t chase the ball, but protect the central space. Protecting the space allows; 1) to maintain your momentum against the opponent which can help you get goalside 2) maintain a line of travel that is parrel to the direction of the ball/opponent, always keeping eye on the ball both points mean that when the attackers tries to cut towards goal (shift their momentum) you can directly intervene with the momentum you’ve already established, you don’t need to be changing direction — or because you’ve filled the central space, even if you can’t regain/retain the ball, your prescence will push the direction of play away from goal Where most midfielders follow the ball, Kante prioritises the space, because he can recognise/predict what & where the opponent will go in reaction to the environment + their own act tendencies. The best footballers in the world are the greatest anticipators. Raya speaks about Alisson’s ability to ‘smell’ what will happen; his ‘timing’ and always being ‘close to the ball’. Being able to recognise + understand performance patterns in football will allow you to be that ‘one step ahead’ of an opponent, because you’re able to ‘anticipate’ their next action. Mastery over motion.

As requested by Alex Miller yesterday, a look at our out of possession shape in the first half. 1: (10 secs) - Wednesday in a very narrow high block in a 523 out of possession. It only looked like this when the ball is central. Nowrich rotate (change positions during play) a lot and this narrow block denies central rotation. In this clip, they have had rotation in left back position as the CM has dropped into the area and left back on the last line. 2: 20 secs - When the ball went wide or started to move wide, the full back would advance up the pitch to pressure the full back and press full back to full back, whilst the CBs would come out with the Norwich forwards coming in between the lines, as this ball transitions across the pitch you see Sargent come out and Iorfa following tight. Fusire in this clip has come out to mark full back to full back and creating a makeshift back 4. 3: 47 secs - Wednesday get back into their narrow block shape 4: 56 secs - rotation from the front line form Norwich 5: 58 seconds, Palmer comes out of the back line to pick up the rotation and prevent space between lines. As the player turns to our left, Amass starts to come out to pick up full back to full back on the other side. In summary, Wednesday played their familiar 523 blocking shape out of possession but it was much more proactive in the back 5 than we usually see it, with full backs and Cbs following rotations and stepping out of the backline to prevent space between lines. It worked, first half. Norwich combated it a little better second half. Will get a clip out tomorrow of what they did

We've seen many teams across Europe utilizing a 4-2-4 build-up shape as it has many benefits, as explained by Fabregas. It's the versatility that's offered, which is arguably the biggest advantage. If the opponents try to press with a -1, then the free man will try to be found. On the other hand, if they go man for man, there's the option of trying to find players between the lines (if the opposition center backs do not jump quick enough) or play direct for the wingers. I was introduced to this idea by watching De Zerbi's Brighton. Hurzeler still uses it.

A very simple, but excellent clip here of Man City practicing Sub-Principles (Defensive Line Principles) from their Game Model. Not everything has to reinvent the wheel. Notice the full back looking down the line to adjust its height. Look at the age-old principles of play: pressure, cover and balance. Observe advancing and retreating as a line (protecting the space in front or protecting the space behind) to avoid gaps in between line or between players in lines. Identical to the #KingKnightEd sub-principles for the Defensive Line.

Introducing the “Get” action in basketball to lacrosse! The “Get” is a 2man action where a player passes the ball to another player and sprints to go “Get” it back on a handoff. This action has similar concepts and reads to pick and roll, but the picker is actually the ball handler! In lacrosse, we have been experimenting with Gets because it creates so many interesting situations and reads for the players. The way we teach it in small sided games is to have one offensive player declare “I’m shut” and the defense has to face-guard him. From there we pick for the shut off player trying to spring them free for the Get. The ball handler has to engage and control their defender, anticipating the shut player trying to get open. The shut player can backdoor if being overplayed towards the get (rejecting the get), receive a flip, or continue curling around the ball getting open for a late pass. The ball handler can feed the reject, flip the ball, or fake the flip to attack the goal or make a late pass to the shut payer curling to the goal. I’ve seen examples of this run in men’s and women’s DI lacrosse at Ohio State and Northwestern, respectively and I’ve run this myself when I was coaching HS girls lacrosse. You will also see on this reel a sick application for Gets vs. a common big-little invert coverage where the short stick doesn’t go behind with his man and plays “Safety” in front of the net. Gets are fun for the players, are incredible for teaching your players 2man game on and off ball, dealing with double teams, and creativity with passing, and can be used to score goals. I hope you enjoy it! Can you think of other applications for Gets?

Defensive Tracking Drills - Tracking drills begin with a simple block destruction where defenders work over the top. - Players must consistently gain ground by working downhill toward the ball carrier instead of shuffling too far away. - Effective tracking requires maintaining a hunkered or tilted body position with a forward lean while staying on the balls of the feet. - Defenders should stay square to the man they are tracking rather than staying square to the line of scrimmage. - The primary focus for defenders is to track the ball carrier's near hip to properly position themselves for potential cutbacks. - To finish the drill, players must explode through contact, ending with their near foot up and tagging the ball carrier's near knee.

2v2 Score Game! All players start at the 10. Coach throws the ball into 1 of the offensive players. Ball carrier must touch the 20y line then they can score. Offensive player without the ball has to touch the hash or sideline before they can block. Defenders mirror the offense. If you’re on the ball carrier side you have to touch the end zone. Blocker side defender must touch the same time hash or sideline. Sometimes I’m not a fan of 2v2+ drills as there’s too much info to process, but this was a sweet spot of action and reading + reacting. Good drill that’s gonna stay in the rotation for sure!

Mason Fowler’s Favorite Back Take from Turtle When your opponent is playing a tight turtle and it’s difficult to insert a hook directly or thread your knee over their nearside leg to make space, Mason opts for this more advanced back-taking option. He uses his far-side leg between their legs to lift behind the nearside leg and create space, then swivels his hips to insert the hook and secure the position.

AI TENNIS ANALYSIS. A FULL COMPUTER VISION SYSTEM. BUILT ON YOLO, PYTORCH, AND KEYPOINT EXTRACTION. Take any tennis match broadcast, any camera angle, any resolution. Feed it into the pipeline. YOLO detects both players and the tennis ball frame by frame. No manual labeling, no pre-annotated dataset. A fine-tuned YOLOv5 model trained on a Roboflow tennis ball dataset handles the ball - the hardest object to track in any sport. Tiny, fast, constantly occluded. The model finds it anyway. Trackers maintain identity across frames so Player 1 stays Player 1 from the first serve to match point. But detection is just the start. A ResNet50 CNN trained in PyTorch predicts court keypoints from every frame - the corners, service lines, baselines, net posts. Fourteen points that define the entire playing surface geometry. From those keypoints the system builds a homography matrix and warps the broadcast perspective into a top-down mini court with real coordinates. Now every player has a position in real space, not pixel space. Every frame becomes a measurement. Every rally becomes a dataset. Player movement speed - calculated from position deltas between frames, converted to meters per second through the homography. Ball shot speed - measured from the ball trajectory across consecutive detections. Number of shots per rally - counted automatically through ball direction changes. All of this rendered live on the video as an overlay. A mini court in the corner showing both players as dots moving in real time. Stats updating after every point. OpenCV handles the rendering. Pandas handles the math. PyTorch handles the intelligence. YOLO handles the eyes. No Hawkeye subscription, no court-embedded sensors, no tracking chips in the ball. A Python script, a trained model, and a GPU. The full code is on GitHub. The tutorial walks through every module - from ball detector training to court keypoint extraction to the final statistical overlay. Professional teams used to need broadcast deals and proprietary hardware for this kind of analysis. Now you build it in an afternoon with open-source tools. Trading here: Computer vision didn't just enter tennis. It made the expensive stuff free.

Pressing, transitions and goals in Canada! After the hiring of Jesse Marsch this week by Canada Soccer , there has been lots of talk about pressing and transitions in the football community. This is THE style of play that we have used for the last 5 years with Alliance United FC in @L1OMens and will give you some insight in how this can look. We went away from the 'possession' based 1-4-3-3 that everyone has been using as the 'best way' to develop players and win games. Many say this is the 'right way' of playing. However, we use the players' abilities and inabilities as the starting point and based on players produced in Canada, within our youth system, this is the way we think will get us the best results and help our players get to the next level. You need to understand youth development in our country to understand what is and what is not being taught to young players. This is not a negative outlook, it is just looking at the reality. Many mistake this style of play as just non-stop pressing and chaos. Yes, these two aspects are important but it is a much more deliberate and planned way of playing that is used to predict where the opposition will play the ball, where the ball can be dictated and what areas the opposition leave open for transitions when they attack. In 2019, I was introduced to Ernst Tanner former Academy Director of Red Bull Salzburg and current Philadelphia Union Sporting Director that has led the club to being one of the top clubs in MLS and arguably the best academies in North America the last few years. Both organisations are known for their pressing and fast transitions in addition to producing top players. He became a mentor to me and gave me insights and education on this style of play. He has changed the way I look at football. Every season we try to recruit players that can play this style that I will describe below and we do not waiver in the way we played. Every game since 2019 Alliance United FC have played either in a 1-4-2-2-2 or a 1-4-4-2 midfield diamond....every game. We have no secrets in how we play. We focus on defending, pressing, forcing teams into mistakes and transition football. It is important to understand that we do not care how much possession we have and we actually want the opposition to have the ball most of the time. Stats in football show that only when a team has the ball 70% or more in a match their is a correlation to winning. Anything less is not correlated to winning in a certain match. In addition, 80% of goals are scored under 5 passes or less and under 10 seconds when regaining possession. We follow the trend! So, here are some important points based on the video: a) Pressing higher up the pitch when possible. All 11 players are committed to the team intention (principles) and if anybody is not committed and does not contribute to this style of play, they do not play. There is no leeway on this. Either you are in 100% in or you are not. All it takes is one player to not commit and the plan will not work. If we do not win the ball on the high press, everyone is to drop behind the ball as fast as possible to restart the press closer to our goal. b) Based on the opponent's scouting we press certain players and decide if will press closer to the sideline and 'pin' the player to the sideline or we dictate the passes and dribbles centrally and 'surround' the player to win the ball in central positions. We also decide if we will sometimes drop lower for the opposition to advance so we can play behind them when winning the ball. This is done if we scout that the opposition centre-backs are slower than our two strikers. This means we will 'outrun' them in the space they leave behind. c) When winning the ball we want to exploit space behind their backline as the priority which means that a player(s) need to be passing options behind the backline and preferably centrally which is closer to the goal, players winning the ball has to look to play the ball to the player furthest up the pitch. Possession is not a priority but scoring goals as fast as possible is. d) When winning the ball we stay as central as possible with passes and dribbling. We use the width of the penalty area (44 yards) as the preferable dimension when transitioning. We want to stay within this width. The wider the team plays the ball, the more time the opposition has to block the middle. PLAY AS VERTICALLY AS POSSIBLE! The emphasis is to get the ball to the two strikers and play 1v1 against the CBs. e) We know that most youth players grow up playing against a 1-4-3-3 which means there is one central striker meaning the centre-backs one back press and one can cover. Against 2 strikers this is not possible and many centre-backs do not have the ability to play 1v1 with space behind them. They are not taught the cues to step and press or drop to protect space behind them. They are never taught at youth level. We exploit this deficiency. e) All 11 players must get up the pitch to close the spaces if we lose the ball from our attacking transition so the opposition cannot transition against us and we can counter-press. f) A goal is the best outcome based on the objective of attacking but at the minimum we want to get a shot on goal from a transition. This is a quick overview of a different way of playing football that Canada will see with the Men's National Team.

Pressing, transitions and goals in Canada! After the hiring of Jesse Marsch this week by Canada Soccer , there has been lots of talk about pressing and transitions in the football community. This is THE style of play that we have used for the last 5 years with Alliance United FC in @L1OMens and will give you some insight in how this can look. We went away from the 'possession' based 1-4-3-3 that everyone has been using as the 'best way' to develop players and win games. Many say this is the 'right way' of playing. However, we use the players' abilities and inabilities as the starting point and based on players produced in Canada, within our youth system, this is the way we think will get us the best results and help our players get to the next level. You need to understand youth development in our country to understand what is and what is not being taught to young players. This is not a negative outlook, it is just looking at the reality. Many mistake this style of play as just non-stop pressing and chaos. Yes, these two aspects are important but it is a much more deliberate and planned way of playing that is used to predict where the opposition will play the ball, where the ball can be dictated and what areas the opposition leave open for transitions when they attack.

LB 7 Cone Tackling Drill - The seven cone drill is specifically designed to prepare linebackers for open field tackling situations where they must effectively manage space. - A fundamental goal of the drill is for the defender to close the distance to the ball carrier, thereby taking away space and reducing the room available for maneuvers. - Coaches should emphasize maintaining leverage by staying inside out on the ball carrier, which forces the runner in a specific direction. - When approaching the ball carrier for a tackle, the linebacker should track the near hip and near number to ensure proper positioning. - The drill highlights the importance of the collision point, specifically teaching players to use the same foot and same shoulder to maximize power and safety. - As players progress to using pads, the drill can incorporate agility bags or crash mats to simulate speed tackles encountered on plays like screens, bubbles, and stretches.
