Barcelona president Josep Maria Bartomeu has told CNN that Luis Suarez's contract does not contain a "no biting" clause.

The 27-year-old Uruguay striker joined Barca from Liverpool for a reported 94 million euros (75 million pounds) last month but will not play for the Catalan club until October as he is the subject of a four-month ban from football.

The punishment was handed to Suarez after he bit Italy defender Giorgio Chiellini during a World Cup match, and could yet be reduced subject to an appeal lodged with the Court of Arbitration for Sport.

As things stand, he cannot train with his new Barca teammates and could not be formally unveiled as he is banned from entering the Camp Nou until his suspension is over.
