Manchester United defender John O'Shea has signed a three-year extension to his current contract.
O'Shea made his United debut in 1999 against Aston Villa
The new deal means the 26-year-old Republic of Ireland international will remain at the club until 2012.
Manchester United manager Sir Alex Ferguson said: "John has developed here and is regarded as one of the more experienced players.
"He has proved through his personality and professionalism he is a credit to the club."
The Waterford-born player's versatility means he has become an integral part of the United squad and can play either centre-half, full-back or in central midfield.
O'Shea said: "I am extending my contract with the champions.
"I have been at the club since the age of 17 and it is a dream come true to play for such a great club.
"I hope to play my part in bringing more trophies here and to continuing the success with this young, exciting team.
"I would like to thank the boss, the staff and the fans for their continued support."
