Uruguay striker Luis Suarez is embroiled in another World Cup controversy after he appeared to bite Giorgio Chiellini during his side's 1-0 victory over Italy.
The Liverpool striker clashed with Chiellini in the penalty area before pushing his head into the Italian's shoulder.
Chiellini immediately appealed to the referee, pulling down his shirt to show alleged bite marks on his shoulder.
Moments after the incident, Atletico Madrid defender Diego Godin scored the game's winner that saw Uruguay qualify from Group D at the expense of the Azzurri.
"It was ridiculous not to send Suarez off. It is clear, clear-cut," Chiellini told Italian television station Rai TV.
"Then there was the obvious dive afterwards because he knew very well that he did something that he shouldn't have done."
Suarez was infamously banned for 10 games after biting Chelsea's Branislav Ivanovic during a Premier League game in April 2013.
That followed a seven match ban he received in Holland in 2010 while playing for Ajax when he was caught on camera biting PSV Eindhoven midfielder Ottman Bakkal.
Four years in ago at the 2010 World Cup in South Africa Saurez attracted widespread criticism when he blocked Dominic Adiyiah's goal bound effort on the line in the final minute of extra time in a quarter final clash with Ghana.
Suarez was shown the a straight red card but Ghana missed the subsequent penalty before being eliminated from the competition in the resulting penalty shootout.
