Luis Suarez says he is getting help in order to control his "impulse" to bite.
The striker, 27, who will make his Barcelona debut against Real Madrid on Saturday, was banned for four months for biting Italian defender Giorgio Chiellini during the World Cup.
Admitting he had a problem, Suarez told the Guardian Weekend magazine: "It is like an impulse, like a reaction.
"I believe I am on the right path now, dealing with the people who can help me, the right kind of people."
Suarez's attack on Chiellini was the third time the Uruguayan had bitten an opponent.
