Manchester United defender Jonny Evans has signed a new three-and-a-half-year contract.

The 24-year-old Northern Ireland international made his United debut as a teenager in the League Cup against Coventry in September 2007 and has now committed to the club until June 2016.

United manager Sir Alex Ferguson said: "Jonny has risen through the ranks to become an integral part of the first-team squad.

"He has developed into a top player for us and has scored a couple of important goals this season too. I am delighted he has signed a new contract."

Evans added: "I'm delighted to sign my new contract. I am so proud to play for such a great club, and there's no better feeling than playing football in this team and winning games."

He added: "I would love to play here throughout the rest of my career."
