Manchester United boss Sir Alex Ferguson says his boot incident with David Beckham was a complete fluke.

Ferguson told Sir David Frost on Sky Sports 1: "We have scored some great goals in my time at United, and I cannot forget Beckham's at Wimbledon. He had attempted the same thing about 10 minutes earlier and I had turned to Brian Kidd and said: 'If he tries that again, he's off.'

"David could get carried away in those days and you had to keep his feet on the ground. Anyway, he does it again, it ends up in the net and Kiddo says: 'We'll take him off then, shall we?'

"As for the Beckham boot - a complete accident. If I could really do that (intentionally kick a boot to hit him near the eye), I would probably still be playing now."
