The 22-year-old has recently been linked with the likes of Arsenal, Chelsea, Real Madrid, Atletico Madrid and PSG.
PSG have reportedly launched a £13.5million bid for the youngster, who ‘is missing his family in Marseille’.
“He is missing his family in Marseille,” Warnock told the London Evening Standard. “If we get a big offer from a club in France that obviously gives him a chance to be closer to them. That would be a big pull.
“PSG have made an enquiry and they obviously offer him the chance to be nearer to home, although there is a Spanish club being mentioned as well.
“As far as his talk of wanting to go to Chelsea or Arsenal, I know he has a lot of friends at Arsenal.
“Flavio Briatore [QPR’s co-owner] is dealing with the negotiations. He is keeping me informed of the situation and at this precise moment he won’t be leaving because no one has met the asking price.”
He added: “My advice to him is to stay until Christmas, get some experience and show people what he can do. That may fall on deaf ears unfortunately. It’s sad.
“I don’t think I have ever spent so much time trying to get the best out of one individual and I think he will regret leaving.”
