Roy Keane and Patrick Vieira were the best of enemies and their rivalry defined both the Premier League and Manchester United vs Arsenal... from THAT tunnel bust-up to squaring up on the pitch at Highbury, we haven't seen anything like it since

Every sport's got one. In tennis it was Borg v McEnroe and in the world of boxing it was Ali against Frazier.

In football, for a time, there was nothing quite as intense as Roy Keane and Patrick Vieira.

You can forget about Cristiano Ronaldo and Lionel Messi as the biggest rivalry in football. Sure they're the best two players in the world, with a competitive streak that has taken both to the summit.
