#6 Luis Suarez bites
I am not actually sure whether I should classify this as a mistake given that the Uruguayan did it three times – and once you do something three times, it is more of a decision than a mistake.
The first incident took place in the Dutch league when Suarez was playing for Ajax. The striker bit Ottmar Bakkal in the shoulder and was given a seven-game ban for it. However, it seems as though one of Luis Suarez’s life’s goals was to bite footballers while playing for three different teams.
The next incident took place in a match between Liverpool and Chelsea while the current Barcelona forward was playing for the former. This time, the Uruguayan bit the Branislav Ivanovic’s arm and was handed a 10-match ban for it.
One would have thought that it was the last time he would do such a thing, but he struck once again – this time while playing for Uruguay – when he bit Giorgio Chiellini in the 2014 World Cup. He was subsequently banned for the next four months and could only return after missing 11 games for his new club, Barcelona.
