You do realise leaks don't have to come from the playing staff. But a ball boy, a tea lady, a board member, physio, anyone. Gossip from around the club can end up leaked by anyone. If Mourinho is being a **** to people in the dressing room, people outside the dressing room but within the club will absolutely know about it. Hell, just someone who works there who happens to be outside a door when he lays into someone is enough to find out. But players will talk about it outside the dressing room, to each other, to other friends at the club, all of which could be overheard by anyone else at the club.
It's pretty hilarious that people try to be all detective and work out who it is... while completely overlooking everyone else who would know at the club.
Also, a player who is playing every week can also hate Mourinho, his style and talk to the press if he wants. There is also another glaringly obvious choice for who leaked it... no one. The press just makes up stuff all the time, all they need to do is put some stories out that people believe could be true.
It seems fairly clear Fabregas wasn't leading any mutiny against Mourinho and his public statements back that up but he wasn't playing well, a paper said he was causing problems and people believed it instantly.
