The Glaswegian told an audience at the Citizens Theatre in his home city that he admired Alan Pardew, Sunderland boss Roy Keane and Newcastle manager Sam Allardyce.

"Pardew at Charlton has got something about him, he is a good young manager," Ferguson said. "Roy Keane has got a good chance, he has something about him.

"Of the older ones, Sam Allardyce is a very influential manager.

"His way of managing is very different. He is very into the sports science, he had about 16 people working behind the scenes at Bolton.

"He knew how many yards his players were running, how many sprints they were making.

"During the game he has got all the figures on a big screen behind the dug-out. He will do well at Newcastle."
