^ I'd say the reason why Mou, Conte and Ancelotti went through tough patches and rebuilds was because they were forced to. Lol. It wasn't necessarily by choice. If those clubs they were in opened their check books they would def would've took the chance to spend like crazy at transfer windows. Lol.
They only difference is, Guardiola has a better hit rate in acquiring players that become successful rather than flops. One of the best examples of this is Kevin De Bruyne.
Pep is like those rich kids who went through the best schools, got the best jobs ; he's been at the top unlike the other managers who started from the scratch, managed scrapy teams to build their way up.
The CV Pep built at Bacelona was enough to set him at the top forever
Often, leading big teams is too difficult a task. The best example is Real, which always has top star players, but few managers have managed to shape them into a single unit.
Although I personally don't like Pep, he did a serious thing in Barcelona, which had top stars at the time. After him, few managers try to control Messi unsuccessfully, but maybe that's why he left there.
Bayern is a league by itself, even Kompani has good results, although it has top players.
Pep is now leaving when it is necessary to rebuild and practically start from the beginning, but with high expectations, which is a special challenge.
He obviously knows when it's time to go out. He would probably be a good trader, because he recognizes the moment to stop-loss.
