Britain's Sports Minister Hugh Robertson and Gordon Taylor, the chief executive of England's Professional Footballers Association, were among those calling for FIFA President Sepp Blatter to resign Thursday following his comments on racism. The 75-year-old Swiss has faced widespread criticism following his remarks Wednesday when he said in two separate TV interviews there was no racism in football and that players involved in any racist confrontations on the pitch should settle their differences with a handshake at the end of the match. Blatter has responded to one of his critics — Manchester United and England defender Rio Ferdinand — by becoming involved in a slanging match with the player on Twitter. Robertson, asked on BBC radio if Blatter should quit, said: “Yes, we've been saying this for some time. This is incredibly serious but it is part of a pattern of behavior.” Taylor said Blatter had now gone too far. “This goes beyond the line. To talk like he did shows he is totally out of tune, and out of time,” he told Sky Sports News. Asked if he should resign, he said: “I think without a shadow of a doubt.” Blatter's comments were televised on the same afternoon as the English FA charged Uruguayan striker Luis Suarez of Liverpool with racially abusing Manchester United defender Patrice Evra last month. Suarez is pleading not guilty to the charge. The FA and police are also investigating allegations of racial abuse by England and Chelsea captain John Terry toward Queens Park Rangers defender Anton Ferdinand last month. Terry denies the accusations. Rio Ferdinand — Anton's brother — was one of many critics, saying on Twitter that he was “astonished” by Blatter's comments. “Sepp Blatter your comments on racism are so condescending it's almost laughable. If fans shout racist chants but shake our hands is that OK?” Ferdinand wrote. Ferdinand also implied in another tweet that a picture on the FIFA website of Blatter with a “black man” was an attempt to limit the damage caused by the FIFA president's comments. Blatter then tweeted back: “@rioferdy5. The ‘black man' as you call him has a name: Tokyo Sexwale. He has done tremendous work against racism and apartheid in Africa.” Blatter gave interviews to broadcasters CNN and Al-Jazeera. Asked if there was racism on the pitch he told CNN World Sport: “I would deny it. There is no racism, there is maybe one of the players towards another, he has a word or a gesture which is not the correct one. “But also the one who is affected by that, he should say that this is a game. We are in a game, and at the end of the game, we shake hands, and this can happen, because we have worked so hard against racism and discrimination.” He also said on Al-Jazeera: “During a match you may say something to someone who's not looking exactly like you, but at end of match it's forgotten.” Blatter attempted to play down his remarks afterwards by issuing a statement where he pledged his commitment to stamping out racism. __
