"A couple of years ago I thought maybe it would be a good thing to spend time with the family, but then it's about timing and opportunities", he added.

Wilkins, who died on 4 April aged 61, won the FA Cup as a United player in 1983, scoring in the final. "It's the greatest club in the world and I thank you for your support over the last 12 years".
"Anthony, I have to wait a bit for more".
