If those quotes are to be believed, and I'd take it with a grain of salt, then I think that's really it for Mourinho. Pogba was going through the motions last night, a few others were too and we needed more from him. Problem for the manager is that players like Pogba are the ones he's going to be relying on to get him out of this tough run of form, which could be where the anger stems from, he's already had to rely on him and Martial a few times this season to get us out of a bad situation.
Fellaini and Matic might play for Mourinho but relatively speaking they're shite, whether he likes it or not they're not the ones who're going to be getting us through patches like this. I'd take Mourinho's criticism more seriously if I thought he wasn't just scapegoating, he wants "mad dogs" then plays the most immobile team possible, it's baffling. He's scapegoating his best player, he probably expects more from him which is fair, but if he's going to call out players then he needs to call them all out ideally.
Shaw, Young, Matic, McTominay and Fellaini were nowhere near good enough yesterday, Lukaku I'll cut some slack because he was actually trying. It's just two sets of rules for Mourinho and the players he likes/dislikes, he should criticise them all equally not singling out people. We've seen it before with Hazard at Chelsea and De Bruyne before he left Chelsea.
