If the right club with the right offer comes calling, Paul Pogba may call it quit with Manchester United this summer.

The Frenchman has refused to rule out a move from Old Trafford in the next transfer window though he is affirmative that Paris Saint-Germain is not a likely destination if he indeed quits United.

Pogba's future at Old Trafford has been thrown into doubt amid concerns over his relationship with Jose Mourinho.

United's record £89 million 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.

Speaking to French TV channel Canal+ on Sunday, he offered no assurances that he will still be a United player next season.

'You're never sure of anything,' he said. 'Contractually, it's on, yes.'

However, on the prospect of joining PSG, the midfielder said: 'Walking on the Parc des Princes? With a club, no for sure,' he said. 'Honestly, it doesn't appeal to me.

Once the most expensive player in the world, only a handful of teams in Europe could afford Pogba's transfer fee and personal terms.
