Manchester United midfielder Darren Fletcher hopes Wayne Rooney will stay at Old Trafford - but has admitted he is worried the striker will leave.
The 29-year-old, who has been forced to take a break from football due to the bowel condition ulcerative colitis, has played alongside Rooney for each of the last nine seasons and rates his team-mate as 'a fantastic player'.
Fletcher has not spoken to Rooney about his future - Chelsea have had two bids for the England striker rejected by United - but admits he does not want him to leave the Premier League champions.
"You do worry he'll leave because he's a fantastic football player, but you leave that to Wayne and the club," Fletcher told Sky Sports News.
"I hope he stays because he's been a fantastic player for Manchester United, and a big part (of their success).
"In all he's achieved in the last 9/10 years since I've been in the squad, we've been in the squad together, so I hope he stays and achieves more things with Manchester United.
Fletcher also revealed that he is keen to see United transfer target Cesc Fabregas make the move to Manchester from Barcelona - but has backed new boss David Moyes to be a success no matter who the club sign this summer.
"He (Fabregas) is a fantastic player, we're always linked with great players," he added. "Whether that's going to happen or not remains to be seen, but I think it's part and parcel of being at the club. We're always going to attract and want to sign big players that will add to the fantastic squad we've already got.
"I think even if we don't sign anyone we have the capabilities and the squad to achieve the success that we want to achieve this season. You're talking about English champions so it can't be too much of a concern."
