He will prove he has balls if he dares to leave all the big ( & out of form) names out in the premier league games.
Seeing Rooney played 90min then there is a chance he might not play against Leicester this weekend. Another thing is Herrera. He played with enthusiasm and full of energy. Carrick was a calm influence and able to dictate the play. So hopefully both of them will get a chance to play this weekend.
Then Pogba can play in his more advanced role. It was shown in the Euros that he can't play in a deeper role. Deschamp was criticised heavily for that and I can't believe JM is doing the same thing.
