A storm over racism in Spanish football erupted on Monday after a fan threw a banana at Barcelona full-back Dani Alves, with Brazilian President Dilma Rousseff and FIFA president Sepp Blatter joining widespread outrage. “The player Dani Alves gave a daring and strong response to racism in sports,” Brazil’s President Dilma Rousseff said in a series of Twitter messages. Such racism had become “unfortunately common,” she added. Blatter also reacted on Twitter on Monday, saying: “What @DaniAlves2 tolerated last night is an outrage. We must fight all forms of discrimination united. Will be zero tolerance at #World Cup.”AFP
