Nani has signed a new four-year contract with Manchester United which will keep him at Old Trafford until at least June 2014. The Portugal international, who joined United from Sporting Lisbon in 2007, has been rewarded for a good season so far with an improved contract.

"I am delighted to have signed a new contract," he told United's official website. "It has been like a dream come true to play for Manchester United. The coaching staff have taught me so much about the game and I'm playing alongside some of the best players in the world. I'm looking forward to winning many more trophies with this team."

Sir Alex Ferguson said: "Nani is an emerging talent within the team and has developed tremendously since joining the club. We are delighted he has signed a new contract and I am sure he will have a long and successful future here at Manchester United."

United are one point ahead of Chelsea and two points ahead of Arsenal at the top of the Premier League going into this weekend's fixtures. Ferguson's team face Bolton Wanderers away in the late Saturday game.
