He told Betfair: "It's really tricky. First and foremost, he'll want to get back into the Man City side and only he can determine that. I don't know what's happening or not happening in training. You hear one or two bits from Pep saying Grealish may not be quite happy with what's happening at City. As a player, when everything is not rosy you have to think, what's best for me and what's best for the team? Do I have to get my head down and win my place back or is it best that I go elsewhere. Only Grealish will know that. Grealish is at a great football club and has had huge success but being left out of this England squad will be a wake-up call for him."
