The new four-year deal will keep Lindegaard at Old Trafford until the summer of 2016.
“I’m very pleased to have signed a new contract,” Lindegaard told the club’s official website. “I’m glad and proud that the manager has shown the confidence he has in me by giving me a new deal.
“There is nowhere in the world I would rather be than right here. The competition for places is tough, as it should be in a club like this. It only makes us better as individuals and, more importantly, stronger as a team.
“It’s what I have dreamt of all my life and nothing makes me more proud than wearing the Manchester United badge.”
“Anders is still relatively young for a goalkeeper but he has come on leaps and bounds since joining us last year,” noted United boss Sir Alex Ferguson.
“There is healthy competition in the goalkeeping department, which is always good for the team, albeit a headache for me!
“I am delighted he has signed a new contract and also delighted to see that he has clearly returned from the summer break in good shape after the disappointment of suffering an injury last season.”
