And Chelsea believe they are in pole position to land the unsettled £25m striker.

United boss David Moyes confirmed this week he has met Rooney "three or four times" to discuss his future.

Moyes has also stressed that £240,000-a-week hitman Rooney - who last night flew home from United's pre-season tour with a hamstring injury - is not for sale.

But, crucially, he has swerved the subject of whether Rooney is happy to stay at United.

And Starsport understands Moyes has yet to convince Rooney that his future lies at Old Trafford.

Moyes was expected to use the club's three-week pre-season to have further talks with the unsettled 27-year-old.

But those plans were scuppered when the club revealed last night that Rooney was coming home.

He suffered the injury in training and scans have revealed the full extent of the damage.

A statement said: "Following a scan on a hamstring injury sustained in training, it has been decided Wayne Rooney should return home for further assessment and rehabilitation."

He has been ruled out for a month meaning he will miss the Community Shield on August 11, the season opener against Swansea six days later and the England v Scotland friendly between those two games.
