I thought that this bullshit with 'his team' started from us with Moyes. Never heard it before, actually never heard fans of other teams giving it as an excuse for the manager not performing.
Anyway, since Fergie left, Pellegrini won the league despite that it wasn't his team, then Mourinho did it in the following season despite having signed less starting players than for us now, then it was Ranieri on his first full season who won the league with a team of misfits, and then it was Conte on his first season. Actually, it was only Saint Pep who won the league with a squad which was 'his'. Even then, on the starting XI, it had just 6 players that he signed. While we have Bailly, Lindelof, Matic, Fred, Pogba, Sanchez and Lukaku, one more than Pep. Same happened all over the world, with Zidane winning an unprecedented 3 UCL in a row, with a team which was assembled from 5 different coaches.
I'll tell you, it is a bunch of nonsense from Moucafe, same as it was from Moyescafe. Manager's main job is to improve the players he has and make a suitable system for them, not sign 25 players before he is supposed to perform.
