Ferguson has spent 21 years in charge at Old Trafford today.
He said: “It’s amazing to think I’ve been here for 21 years.
“I’ve certainly had the key to the door for a while now!
“I guess I have to think about retiring at some stage but I still have plenty of ambition here and these young lads make me feel younger.
“I’m proud of the current team – they need a little bit of direction at times but they’re showing fantastic enthusiasm for the game and there’s a great spirit among them.
“At last Friday’s training session I had to get Carlos Queiroz to tell them to stop because it was too good.
“We were due to play Arsenal the next day and I wanted them to keep that kind of football for the Saturday!”
