Manchester United boss Sir Alex Ferguson admits it's been an emotional week.

The retiring manager concedes his speech to the Old Trafford staff last week was tough for him.

He told MUTV: "Yes, it definitely has been. On Sunday, I did what I had to do and I thought I did it well. I didn't show my emotion too much. When I announced to the staff, I was a bit blubby, you know. I think, funnily enough, the last few days have been hard and Monday night, after the parade, I slept for 10 hours.

"I think it was the first time in my life. I was absolutely gone - knackered! I didn't go in [to work]. I don't know what time it was but I kept feeling the presence of Cathy coming into the bedroom. I think she was checking I was still alive! "
