has refused to rule out a move from this summer, but says he will not join .
Pogba's future at Old Trafford has been thrown into doubt amid concerns over his relationship with . United's record £89million signing has been left on the bench and substituted on a number of occasions during a disappointing season.
The Frenchman, who was again below-par in United's defeat to Chelsea in the FA Cup final at Wembley, admitted that he had some 'mental' issues over his relationship with Mourinho.

'People thought it was wrong but a coach and player don't have to be best friends. One is not forced to go to the restaurant together. I had some problems – it's mental.
