Luis Suárez has been criticised by Uruguay football great Alcides Ghiggia, the last survivor of the team which defeated Brazil to win the 1950 World Cup, and the man who scored the winning goa in the Maracanã. Suárez is set to learn his fate on Thursday as his lawyer claimed calls for the Uruguay forward to face a lengthy ban for biting Giorgio Chiellini were part of an Anglo-Italian conspiracy. Ghiggia has become the first Uruguayan public figure to come out against the striker. Suárez "plays well but he has done things that are not normal for a player nor for a football game," Ghiggia said. "This boy's clearly not right in the head. That's just not something you do on the pitch. I think Fifa can sanction him. "He already did it before in England and now he's done it again. It's abnormal. It's a football match – not a war or a fight." However, Uruguay's president Jose Mujica weighed in to the global controversy on Wednesday, saying it was unfair to judge him retrospectively for biting an Italian player when other incidents went unreviewed. Mujica, 79, a former guerrilla fighter and political prisoner, added that Fifa should not use television evidence to retrospectively punish players. "I didn't see him bite anyone and, in football, I was taught that you obey what the referee says," Mujica said.
