Everton boss Roberto Martinez says Liverpool striker Luis Suarez needs help after his latest biting incident.
Suarez appeared to bite Italy defender Giorgio Chiellini during Uruguay's World Cup win yesterday.
"There is no doubt that the quality of the talent that he has," he told ESPN.
"He can win games single-handed and he's got that focus, that mentality that he can get back from a situation he shouldn't have derived.
"But the behaviour, I just seriously think that he needs help. If you cannot control yourself in those moments, you need some sort of help because that's just unacceptable on a football pitch."
He added: "This is a behaviour that has happened already two times and Luis Suarez, as a wonderful footballer that he is, has been banned twice. It has been such a controversial way of acting on a football pitch that you see it again and everyone feels upset."
