Tottenham boss Harry Redknapp rates Manchester United's Sir Alex Ferguson as king of the heap.
"His record tells you that, without doubt, he is the most successful...he would certainly take some beating, wouldn't he?" Redknapp told Hotspur magazine.
And Redknapp always enjoys his visits to Old Trafford.
He adds: "It's a special place, a magnificent stadium...it's got something about it. I go all the way back to the Busby Babes, all those great players. It's got that special feeling about it."
