The player is to blame but I think it's pretty easy to see why he may have lost will/hope. It's entirely reasonable for him to want to leave given his age and the role he has in the team. Mourinho has been playing him in pre-season, yeah because half of our attacking options are on vacation. The second everyone is ready, it'll be Sanchez on the left wing, Lukaku up top and him fighting with Rashford to be the first sub off the bench, which is nowhere close to what either of them need right now. And he looks like a player who knows that is his situation. If he scored in every pre-season game as a striker, Lukaku would still take his spot. Same as Sanchez on the left. If he scored a hat trick on the first game of the season, at best, he'll be pushed to the right wing to try and make an impact there. His 2 positions where he can play, he has no way into the team. It's a hopeless situation for him and he plays like that which makes it so much worse as he has no chance to actually work his way into the team at all like that either.
