The 26-year-old, who has another year to run on his contract has held talks over extending his stay at United, but has so far yet to put pen-to-paper on a new deal.
"We have already had one meeting about my contract," the French international told the News of the World. "The directors know my position. I give my all for this club.
"I love the club and its winning mentality.
"When I play video games I cannot be another English team. It's a crisis when we lose one match here.
"I haven't lost two in a row in two years. There's incredible stress.
"Even if we were to draw against a team like Arsenal, we would get a volley from the manager.
"But that does not mean everything. I may leave next year or in two years."
