Manchester United boss Sir Alex Ferguson is confident he'll be busy in retirement.

Ferguson revealed he will obviously keep watching the Reds but will also focus on other interests away from the pitch.

"I've got 11 grandchildren and it keeps Cathy busy anyway!" he joked on MUTV. "It's great and will be lovely seeing them grow up. Callum, I think, is nearly three and Frankie is almost three but then Jake is 19 so we've got quite a spread of ages.

"[As for other interests], [my son] Jason deals with the business side of it and we've had a lot of enquiries after the case study I did with Harvard University. It was very interesting and I enjoyed that. I thought it was quite a challenge to me and I still need challenges of a different nature so I'll continue with that.

"I'll probably go back and do some language lessons - things like that I'll enjoy. Another thing is the vineyards - I've got to drink them all dry!"

There was one final message for the supporters ahead of the weekend encounter against West Brom.

"They've honoured me in a fantastic, special way," he stated. "Last Sunday is something the Fergusons will never forget. I can't lose my last game!"
