If Pogba is not giving him what he wants now, he will not play, Keown told the Mail. If he is not playing, it would not come as a surprise if he left in the summer.
Mourinho has to do more to make a success of Pogba or admit that this move did not work out for either party.
I do not know if he will ever be the player Mourinho wants him to be. Yet given the fee and that the club stuck their neck out to re-sign him, Jose must work harder to make a success of Pogba.
He is a master at getting the best from players — just look at the 20 major trophies he has won. He usually gets it right but when he does not, it can go spectacularly wrong.
