Personally I don't think Pep will find things any easier at City. Yes, their current crop of players are much better suited to his style than at Bayern, but he's going to find stiff competition from UTD and Chelsea with two coaches who already know his tricks and how to exploit them.
Plus if he thought it was hard to teach the German's tiki-taka, wait till he tries it with the Englishmen, the inventors of punt and run football
Not saying he can't succeed there nor that English football hasn't had their innovators in the past.
I'd say the biggest advantage over Bayern is he won't have the weight of being the identity of German football to a club that needs an identity.
I just have a feeling this season won't go well for him. Ripping the German's from a Bavarian club and replacing them with inconsistent and temperamental South Americans certainly won't win him any fans, especially as it's two new players learning a very complex style of football.
He should just force a move to the Brazil NT. That seems to be the sort of players he wants to work with and especially since he will be coaching Neymar, thereby indirectly aiding Barça, I think he'd like nurturing him to take Messi's throne.
