Luis Suarez should seek professional help to stop him from repeatedly biting opponents, FIFA general secretary Jerome Valcke said . Asked for his views on Suarez's four-month global ban for biting, Valcke told reporters: "I think he should find a way to stop doing it. "He should go through a treatment. It is definhttp://192.206.4.106/cms/article/add_img_gal.php?update=33437itely wrong." Uruguay striker Suarez was kicked out of the World Cup for biting Italy defender Giorgio Chiellini during a Group D match. It is the third time in Suarez's career he has been banned for biting. Valcke dismissed comments from Chiellini who said the punishment on Suarez -- the heaviest sanction of a player at a World Cup ever -- was too harsh.
