Sir Alex Ferguson has already tied defender Rio Ferdinand to a long-term deal in the last week and has now convinced Carrick to stay until at least 2012.

"I am delighted Michael has signed a new contract," said Ferguson.

"Michael has been outstanding since joining us from Tottenham and it is great to know he will be a part of this squad for many years to come."

Carlos Tevez and Patrice Evra could also be handed new contracts in the near future.
