Barcelona striker Luis Suarez says he has talked to specialists about his behaviour and insists there will be no further biting incidents.
Suarez is serving a four-month ban for biting Italy’s Giorgio Chiellini at the World Cup – his third biting offence.
“I say to fans, don’t worry, because I won’t do that anymore,” he promised.
“I spoke to my psychologist and he said I had to face it and say sorry. I did – now I would rather focus on the present, which is Barcelona.”
The Uruguay player was banned for four months from any football-related activity, plus nine international matches, for biting Italy defender Giorgio Chiellini.
Suarez’s subsequent appeal to the Court of Arbitration for Sport was thrown out but he is no longer excluded from “all football-related activities”, which allowed him to make his Barcelona debut as a 75th-minute substitute in the 6-0 friendly victory over Mexican side Club Leon on Monday.
