The Reds' captain says the boss has had a big influence on football in general, not just United during his 26 years in the Old Trafford hot seat. And Vidic feels very lucky to have had the opportunity to work so closely with Sir Alex.
"He's a great example for all managers and it's great to work with him," Vidic told MUTV.
"You learn something new from him every day - I have learnt a lot from him, not just as a footballer but in life [in general]. He gives all the players great confidence and belief and he does all he can to get the best out of his players. I think this is his biggest strength. He has faith in us and he trusts us and I'm really glad I have been able to spend nearly seven years working with him. He is a winner."
MUTV is showing the statue unveiling live on Friday from 13:30 GMT. The channel's 90-minute programme will be free-to-air for Sky customers.
