Manchester United directors have informed manager Sir Alex Ferguson he has the job for as long as he wants.

United chief executive David Gill backed the 66-year-old to forget retiring even if he wins his second European Cup in Moscow next week. Gill also said the club's owners, the Glazer family, were preparing to fund Ferguson again this summer - starting with a possible £20 million move for Manchester City defender Micah Richards.

Hailing Ferguson's achievements at Old Trafford as phenomenal, Gill said: "We never discuss it (retirement). It came up a few years ago, when he decided to retire, but thankfully he reversed that decision.

"He is on a 12-month rolling contract and we are very happy with that. But retirement never comes up in our conversations."

He added: "He has been here for over 21 years now. He has built many teams in that time and we have had that stability throughout the club as a whole.

"Ten titles is phenomenal and hopefully there are more to be won."
