Guardiola has played the exact same type of football since he became Barca B manager.
If people think Pellers is a zealot who won't change style, they'll be rioting in the stands when Pep comes.
This simply isn't true, against Dortmund this season the coach said they played how you expect them to play but then when Dortmund found a way to get close to them they switched to playing a long ball over the top in behind the defence and they couldn't handle it. Against Arsenal in the champions league when a left back got injured and then got replaced he specifically targeted said player because he wasn't warmed up and up to the pace of the game which resulted in a goal. Pep plays the same style but tactically he is completely different depending on the players he is facing from game to game.
