Well, I know people like super serious Coaches, but Bielsa just sent an sms to Amlalfitano saying something like "Don't ever come back to training. I don't want you even if I never met you. Can't fire you, but it's as if you are. Ciao byebye GG". So yeah now he complains that said player is furious to be treated worse than a dog.
Bielsa is a prick. I would not like a coach like him here. Even Vahid Halihodzic doesn't act like that.
