Manchester United defender Rio Ferdinand has shocked the Old Trafford club by admitting that he may not sign a new deal.

The former England international’s current contract expires at the end of the season and manager Sir Alex Ferguson has indicated he will offer him a new deal, but Ferdinand has revealed this might not happen.

The former West Ham man has struggled to maintain fitness over the past couple of years and, despite appearing able to play regularly once again, he admits he will have to see how his body feels later in the season before making a decision.

Ferguson recently stated his belief that the 34-year-old could still perform at the highest level “for two or three more years” and it was widely believed that a new deal would be forthcoming and signed, but Ferdinand’s recent words have put this in doubt.

“It's always good to hear the manager say things like that but you have to take every week and month as it comes,” he is quoted as saying in the Daily Mail.

“The best thing I can do is to look at it at Christmas, and then again in the summer to see how I'm feeling and go from there.”

Ferdinand signed for United in 2002 from Leeds United in a deal worth nearly £30million and has made over 400 appearances for the Red Devils.

During his time at Old Trafford, the central defender has won five Premier League titles, two League Cups and a UEFA Champions League winners’ medal.
