Luis Suarez's lawyer is adamant that his client's ban for biting will be reduced.

The Uruguayan striker was given a four-month sanction by FIFA after he bit the shoulder of Italian defender Giorgio Chiellini during a World Cup group game in June.

Suarez has since moved from Liverpool to Barcelona for around £75m, and his legal representative, Daniel Cravo, thinks that the Court of Arbitration for Sport will help in getting the ban reduced.

Cravo told Radio Globo: "I believe that the sanction which affects his work at a club level will be revoked. There is no precedent in history to justify it.

"There was dissatisfaction with how other incidents had been treated at the World Cup and Suarez paid for them. Not even the sanction of Zinedine Zidane in 2006 or those of Leonardo and Mauro Tassotti in 1994 were as severe.

"I think FIFA wanted to show they could take action. I am going to try and reduce his ban with Uruguay – nine [international] games is too much and would stop him from playing until 2016. [The CAS] is totally different and on various occasions in the past they have taken completely different decisions to those which have been taken by FIFA."

Suarez's case will be heard in a Swiss court on Friday.
