LONDON (AFP) - Manchester United midfielder Darren Fletcher admitted on Tuesday that he is worried by reports that team-mate Wayne Rooney could be about to leave the English Premier League champions.

United on Monday said that that they had "immediately rejected" a second bid, worth an initial £25 million (S$49 million) from Chelsea for the England striker. With the Red Devils braced for a third bid from the Blues, Fletcher has said that he would hate to see Rooney leave Old Trafford.

"You do worry he might leave because he's a fantastic football player," said the Scottish midfielder. "Personally, I hope he stays because he has been fantastic for Manchester United and a big part of all we have achieved in the last nine, 10 years since I have been in the squad."

Rooney has been ruled out of United's friendly against Swedish side AIK in Stockholm later on Tuesday after injuring his shoulder in a behind-closed-doors match against Real Betis on Saturday.
