Liverpool striker Luis Suarez has been fined by his club after biting Chelsea defender Branislav Ivanovic on the arm during yesterday's 2-2 draw against Chelsea at Anfield.
But the anger-prone Uruguay has had his share of past controversies:
January 2013 - Handles the ball prior to scoring Liverpool's winner in the FA Cup third-round tie against Mansfield Town.
October 2012 - Celebrates a goal against Everton by diving in front of Everton boss David Moyes, who had earlier claimed that "divers" were putting fans off the English game.
February 2012 - Suarez refuses to shake Manchester United player Patrice Evra's hand before kick-off at Old Trafford.
December 2011 - Seen making an offensive gesture towards Fulham fans.
At this time he had already been charged by the FA over allegedly racially abusing Patrice Evra, although not yet punished. He was handed a further one-match ban for the gesture.
October 2011 - Alleged to have racially abused Manchester United's Patrice Evra during a Premier League match. Later found guilty by an independent regulatory commission and banned for eight matches and fined £40,000.
October 2011 - Involved in a tackle with Everton's Jack Rodwell and goes down with apparent minimal contact. Rodwell was then sent off.
November 2010 - Handed a seven-match ban by the Dutch FA and fined by his club Ajax for biting PSV Eindhoven midfielder Otman Bakkal during an Eredivisie match.
July 2010 - During the 2010 World Cup quarter-finals, Suarez prevents Ghana's Dominic Adiyiah from scoring in the final minute with a deliberate handball on the line and is subsequently sent off.
A penalty was awarded but missed by Asamoah Gyan and footage showed Suarez celebrating on the sidelines. Uruguay eventually went through to the last four on penalties.
November 2007 - Joins Ajax from Uruguayan side Nacional but he is later suspended by the Dutch giants after a half-time dressing-room altercation with team-mate Albert Luque.
February 2007 - Makes his international debut for Uruguay against Colombia but is sent off in the final minutes after being shown a second yellow card for dissent.
