Manchester United is pleased to announce French full-back Patrice Evra has signed a four-year extension to his contract, keeping him at the club until at least June 2012.

Sir Alex said: Patrice has been a key part of the Clubs success in the last two seasons.  He's developed into one of the best full-backs in world football and his infectious personality has helped build the incredible team spirit that exists at Old Trafford.

Evra, 27, was delighted to pledge his future to United, claiming "the last two-and-a-half seasons have been the start of a dream".

"It's a pleasure and an honour to be part of this fantastic side and to be coached by Sir Alex Ferguson and his staff," he said. "United is more than a club its a family I am proud to be a part of and that's why it's always been a first choice for me.

I declared when I arrived that I was coming here not just to play but to win, and United is the ideal place to realise such a dream. It's a privilege to play in front of our fantastic fans and I'm sure the success we've earned in the last two seasons confirms the history of this club and will be the start of something even more special.
