The Liverpool forward has been accused of biting Italy defender Giorgio Chiellini on the shoulder in his side's 1-0 victory in their final Group D match - the third time the striker has been involved in such an incident in his career.
However Suarez's lawyer, Alejandro Balbi, has confirmed that he is working on a defense and has insisted the confrontation has been blown out of proportion as a result of the Liverpool man's history.

"We don't have any doubts that this has happened because it's Suarez and secondly because Italy was eliminated," Balbi, who is also a Uruguay FA board member, told local Uruguayan radio. "There's a lot of pressure from England and Italy. We’re polishing off a defense argument.
"There is a possibility that they ban him, because there are precedents, but we're convinced that it was an absolutely casual play, because if Chiellini can show a scratch on one shoulder, Suarez can show a bruised and almost shut eye.
"If every player starts showing the injuries he suffers and they open inquiries for them everything will be way too complicated in the future. We’re going to use all the arguments possible so that Luis gets out in the best possible way.”
