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."
