The England defender has signed a deal until until 2013, with manager Sir Alex Ferguson fuelling a growing belief that the 29-year-old has been earmarked as the club's next captain.

Ferdinand has taken the skipper's armband on a regular basis with Ryan Giggs used sparingly and is likely to lead United into their Champions League final meeting with Chelsea on May 21.

And though Gary Neville will be back from injury next season, the implication is as soon as the long-serving full-back stands aside, Ferdinand will get the job full-time.

"Rio has matured into his role at the club and has shown, when needed, what a great captain and leader he can be," said Ferguson.

Ferdiand said: "It is a great honour to be part of this trophy-winning team and to share in the success, which I am sure will continue for many seasons to come.

"I would like to thank the manager, the coaching staff, the players and the fans for the tremendous support they have given me since I joined the club."
