We can confirm that Matt O'Riley has joined English Premier League side, Brighton & Hove Albion. Everyone at #CelticFC would like to thank Matt for his vast contribution and efforts for the Club. Best of luck and thank you, Matt 🍀

He came, he saw, he conquered... The club should be using him as a blueprint for every highly rated young player who wants to better themselves, two full seasons & he transformed from a £1.5m player into a £30m one. Best of luck to Matt, I suspect he'll go to the highest level.

We will look after him 🤝

Miss you. Love you. Best of luck, Matt💚

Go and smash it son 💚

You are a great club, we will look after him 🍀 🤝

Conducted himself brilliantly his whole time at the club. What a genuine and lovely guy. Devastated he's gone but can't wait to see what this lad achieves in the game now. Future CL winner? I think so. Could play anywhere in the future. The World's his oyster now. HH

Classy post. Classy club. We promise to look after him. 💚

As well as being extremely talented @mattoriley8 comes across as one of the good guys on and off the field. Wish him every success 🍀👏
