World Cup row between Brazil and Fifa worsens as general secretary Jerome Valcke calls government 'puerile' But Brazil has not had the last word. Valcke remained defiant at the meeting of the International Football Association Board, accusing Rebelo of deflecting attention from the substance of his remarks. Valcke had expressed Fifa concerns that political obstacles to the construction of accommodation and transportation infrastructure appeared a long way from being overcome. Fifa's principle beef is that, five years after it was due, politicians have still not passed the enabling bill that would be the catalyst for World Cup-related developments and for a coherent security plan. "Why doesn't he deal with the issue," Valcke said. We have compromised on a number of things about ticket discounts for elderly people and the wording of guarantees. But there is no way we cannot receive a guarantee about security or terrorism. That is not the responsibility of Fifa. It is not an option not to have this bill. If (I'm) the problem because nothing has happened over the five years ... because I made, wow, one comment saying things are not working well and I for once said exactly what is happening in Brazil. If the result is they don't want to talk to me any more, I'm not the guy they want to work with, that's a bit puerile. The row has cast a cloud over the business of IFAB, wherein a major step forward was taken over the long-awaited issue of goal-line technology. The Premier League is bullish about its prospects of introducing the systems to its ground at the earliest outset. But Alex Horne, the Football Association's general secretary, has sounded a note of caution. He indicated that timescales might make it difficult for English clubs to proceed with the devices in time for the 2012-3 season's opening. If so, Horne has said, it is unlikely Premier League clubs would seek to introduce the technology in mid-season. In which case, Valcke indicated, the approved technologies would be used for the first time at the Club World Cup in Japan in December. Coincidentally, that is the same nation as the headquarters of Hawk-Eye's parent company, Sony. A "special" meeting of the IFAB on 2 July will clear the way for the technologies to be used, provided test results in the meantime justify such approvals. Six other companies which have so far failed to pass accuracy requirements have been invited to continue testing and to apply for licences in future. At the July meeting an official headscarf for women players in Islamic territories where hijab-wearing is compulsory will also be endorsed. The Fifa executive-committee member Prince Ali of Jordan gave a presentation to IFAB to explain how tensions between religious requirements and Fifa's rules outlawing headgear have been a barrier to the development of the women's game. Other developments to football's law book arising from the meeting here include the introduction of "rolling substitutions" permitting an unlimited number of replacements throughout the amateur game. "The new amendment is in terms of grassroots football to modify the number of substitutions and they can roll on and off the pitch," said Horne. This is very important for us to attract and retain people in the game.
