You have to learn how to play with your team mates, how to read what they are going to do next. Like Big Mac himself said, he didn't know how Jones was going to cross that ball otherwise he would have been able to anticipate it. Its also why strikers talk about developing an understanding.
On top of that, he will get fitter and stronger and he will run his b*lls off for MM because MM has faith in him.
I do agree with that i do hope i am wrong about him - but he has had 1 good game and am comcerned if he doesnt turn out well the club have him all next year as well
