Well don’t you see Pep already inherited a great squad in Bayern? They just won treble before Pep took over! It’s not like he has to spend alot to rebuild or anything. They are already the best team in Europe.
While at City, they are super rich anyway, and one of the best team in England before Pep took over. The style over there is already similar to Pep possession football, so there’s not much fundamental fixing need to be done. He could also spend and buy any players he wants, and he did spend a lot.
We are at tight budget, and we don’t have CL next season, and we have huge pile of shit to fix, and we are going to change to completely different style of football. It’s totally different story here.
It’s better to bring the players he trusted first, easier to implement his system here, then when we have extra funds to spend, he could buy players elsewhere who he think would fit. But now, we have too much shite to fix, and we can’t afford too many risk to take.
