Sir Alex Ferguson will reportedly rebuff any approach by Manchester United to try to bring him back as manager if they replace David Moyes.

Despite pressure mounting on the current boss after a poor run of results, the 72-year-old insists that he will not go back on his decision to retire at the end of last season, according to The Mirror.

A club source is quoted as saying: "There is no chance that Sir Alex will return as manager.

"He remains fully behind David Moyes and is always there should the manager want to seek his advice. Sir Alex is enjoying his retirement."

Moyes is currently in the first year of a six-year contract after succeeding Ferguson in the summer.
