Guardiola in 2007.

The worst thing about positional play is the coaches that are miles worse than Pep that have adopted it, that’s the real issues with it

The pep now is very different from the pep then “positional” play evolved a lot.

Being myself a searing detractor of positional football, it's clear that Guardiola knows about players, and he knows how to take the most out of them in almost every case.
