CHARLES GRAHAM - You will be tough to follow, Sir Alex

SO the hairdryer is finally to be switched off.

Sir Alex Ferguson, one of the greatest football managers of all time anywhere, is calling it a day after 27 years at Old Trafford.

Numerous clubs and fans will look enviously at his remarkable track record and the fact that the Man United board had the patience and nerve not to boot him out when he didn’t deliver instant success (a lesson to many with more of a revolving door attitude to managerial performance).

Not only has he been a great strategist, but he has also been a master of the successful mind games he played with opposite numbers.

The Kevin Keegan wind-up was a classic of its kind.

It will be fascinating to see how Ferguson’s successor will fare, both in terms of trophies and shelf life. One thing is for sure, it’s a heck of an act to follow.
