Pep's stubborn refusal to change is hurting City, much to my delight.
Pep is obviously a very good coach, the football he prefers is not suited to every player and league though. It's quite clear that English football lends itself to teams that have pace and power. You can argue about whether that makes it old-fashioned, backwards or whatever. Facts are facts though and Pep just won't accept them.
Pep in another league, where possession and technique matter more, would do better. However, Pep in this league has gone full Van Gaal. He's more interested in his philosophy being proven right than winning games the easiest way.
