All this can be solved by just giving him opportunities, its not rocket science.
Reckon its nothing to do with the club, Silva, the city etc. He didnt get a look in here, went to Leipzig who gave him more opportunities there in a few months than we did in over a year. He comes back here and we sign a £40mill player in his position and another Brazilian international who has played there a good bit. He's bound to be disheartened.
The problem is that Silva is telling him he's wanted and he will get opportunities but Lookman doesnt know that for sure, where as at Leipzig he knows 100% that he will.
Reckon once the season starts and he (hopefully) gets a good bit of playing time then he will be happy.
