Roy Keane's attack on Alf Inge Haaland. It's actually more of a feud than a straight scrap. Keane did his knee ligaments in a match against Leeds when Alfie was playing. Even though Alfie didn't even touch him, Keane held a grudge for sixteen months before exacting his revenge with this tackle that contributed to ending Alfie's career. btw Roy Keane's full first name is Royston.
