Luis Suarez's controversial career

Liverpool striker Luis Suarez has been forced to apologise for refusing to shake the hand of Manchester United's Patrice Evra.

Suarez, who had previously been found guilty of racially abusing Evra, snubbed him when the sides met again.

Controversy is nothing new to the Uruguayan star, who was dubbed the 'Cannibal of Ajax' in 2010 for biting an opponent's neck.

Earlier that year he denied Ghana a match-winning goal in extra-time of the World Cup quarter-final with a deliberate handball.
