France left-back Patrice Evra has signed a new four-year contract extension to keep him at Manchester United until the summer of 2012.
The 27-year-old moved to Old Trafford in January 2006 from AS Monaco and helped the Red Devils to win both the Premier League and the Champions League last season.
United boss Sir Alex Ferguson told the club's official website: "Patrice has been a key part of the club's 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 himself added: "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.
"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.
"I'm sure the success we've earned in the last two seasons will be the start of something even more special."
