If half of that 100m went to Tammy fucking Abraham I think the management is at fault as well, no? You cannot really put the budgetary blame on a coach. People keep doing that thinking that football is like a video game and there's total freedom and control from the coach.
The irony is that the last season Mourinho had much of a say in the transfer market was 2008-9 when he got Quaresma. Even Mancini was a management decision as the idea was that we'd be playing 4-3-3, with Mancini and Figo on the right and Quaresma with Obinna and Jimenez on the left. He also wanted a Deki replacement in case he was gone (between Deco and Lampard) but the management wanted to push for Schweinsteiger instead.
Conte on the other hand had this luxury at Inter, wanting to bring in Lukaku, Lazaro, Kolarov, Vidal and Young in particular. His only request that didn't come was Milinkovic-Savic, and that's mostly because he himself prioritized on Lukaku.
Mourinho? At Real Madrid, zero input in transfers. Everything was done from the upper management. He was there to coach.
At Chelsea, they signed a bunch of players but none were really his personal requests. Probably wanted to have veterans Eto'o and Drogba, but that's about it.
At Manchester United, he had absolutely no say in practice. He asked for a defensive midfielder, they got him Pogba. He asked for a ball playing center back, they didn't get anyone. He asked for Perisic, they signed Fred. Complete disarray because Woodward and his precious committee did not see eye to eye with Mourinho.
At Tottenham he didn't decide on players but at least he was on board with management on characteristics and positions. Team played well at times, shit at other times. It's Tottenham. Their players are messed up in the head, they think they are in Real Madrid.
At Roma we've said it multiple times that he needs at least 15 new players. Last night he said it himself.
He needs to fix the roster, if the management is on board.
He needs to fix the mentality, yet they're losing crucial players.
He needs to fix the results. So far they're doing okay, but it's not like anyone could have said that Roma can make top 4 before hiring Mourinho. Now it's sort of expected even if their squad is behind Inter, Juventus, Napoli, Atalanta, Milan, Lazio and on par with this season's Fiorentina.
Mourinho doesn't really ask for specific players. He just asks of players to change tbeir mentality. For clubs like Man Utd, Chelsea and Tottenham that's hard for more than a few months. For Roma, it'll show, but I've doubted his potential there. It's a good environment as long as he can get the core players on board and the management decides they want a CL team rather than just to run a club.
