The England striker has been linked with a move away from Old Trafford ever since Sir Alex Ferguson revealed the striker asked to leave in May, and speculation over his future has intensified after he flew home from United's pre-season tour of Asia with a hamstring injury.

"Manchester United isn’t about Wayne Rooney. Manchester United is about the team, the club," Moyes said.
"We are talking about him now, and rightly so, but I won’t allow Wayne Rooney to become more important than the football club."
The Scot, who lost his first game in charge to a Thailand All-Stars side on Saturday, then suggested the England international will be second choice to Robin van Persie again next season.
"Overall, my thought on Wayne is that if for any reason we had an injury to Robin van Persie we are going to need him and I want as many options as possible," he added.
"Wayne’s got a major part to play because we need to try and get him as many goals as we possibly can.
"It’s going to be a time to see how I work with him. Wayne, in a way, fits that as well. We need to see how it works. Maybe in a year’s time we might have to look at something else."
