I do not buy the "he is immature. He has an attitude problem". It's just convenient journalism. When he was scoring he was praised for having a calm head and proffesional attitude then suddenly he had a bad attitude. It's just making up a story that sells.
No shit he was fading away. He was 18 in a terrible team. If Jose doesn't play him this season he will be gone and have a very succesful career whever he goes.
He is your typical LAD. Wears snapbacks, talks in slang and loves to hang with his "bros" and bang hoes.
When he was playing well, he was showing a maturity beyond his years in terms of decision making. He was an unknown quantity when he first came through. Teams started figuring him out more and more as time went on. You receive more respect from defenders and players double up on you.
I think the hype went to his head. He became more and more of an individual player. This is what let him down at BVB. They attack as a unit, but he was slowing down attacks by dallying on the ball and trying to dictate things to his own rhythm. They like sharp, crisp attacks.
It happens all the time in football. It could even happen to Rashford, but he has shown great mental strength so far.
And his attitude was called into question when Ferguson went on a rant aimed towards him during a FA Youth Cup match a few years back.
