Of course he should, but give them a way back and don't freeze them out forever costing the club millions of money. Look at how Chelsea treated the Lukaku situation. What Lukaku did is 1000 times worse than what happened with Auba and Özil and yet he's still at Chelsea and is even scoring recently again. Will he stay at Chelsea? No but now they can still sell him for a decent sum.So he shouldn't fall out with his CAPTAIN when he turns up late for training? He shouldn't fall out with prima donnas like that Özil? Nope, no time for people like that. Let them go to Man Utd with their attitude.
