Cole believes Fergie has ‘revolutionized’ football during his 25 years at Old Trafford.
“I think he’s revolutionized football. When people stay manager at one club for 25 years and how’s he done it, you’ve got to move with the times,” Cole said.
“We’ve got generations that have changed from when the manager first started managing football to where he is now, it’s exactly the same way but in a different manner.
“You can only take your hat off to him.”
