FIFA audit and compliance chairman Domenico Scala has resigned in protest against a power grab by President Gianni Infantino over control of independent panels that monitor the scandal-hit soccer body. Scala's walkout Saturday comes amid claims of tension between the two men over Infantino's salary. It marks a major challenge to the integrity of Infantino's presidency since he was elected to succeed Sepp Blatter in February. Scala, who has monitored FIFA's billion-dollar annual spending since 2012, described his resignation as a "wake-up call" for people working to reform FIFA. Tensions between the two Swiss-Italian men were exposed Friday at FIFA's annual congress in Mexico City. Member federations voted in new powers to Infantino's ruling council to fire Scala and ethics committee leaders who investigate corruption claims. Those independent officials have been seen as a key check on FIFA since their appointments were the main achievements of a Blatter-led round of anti-corruption reforms in 2012. "I am consternated about this decision," Scala said in a resignation statement, citing Friday's move, "because it undermines a central pillar of the good governance of FIFA, and it destroys a substantial achievement of the reforms." In a speech Friday, Infantino declared FIFA's corruption-fueled crisis to be over. Infantino later defended his new powers to remove key people overseeing his work when he was questioned at a news conference. "Those that are making the comments have not really understood what we are doing," Infantino said in Mexico City, adding his council would have the powers for only one year. "The judgments need to be made by the quality of the members who are sitting on these boards rather than by making speculations or putting intentions in the minds of people which are far from the reality." Still, the tactic was criticized by former FIFA anti-corruption adviser Mark Pieth who helped bring Scala, then a pharmaceutical industry executive, to FIFA four years ago. "(Infantino) is actually exactly working like (Michel) Platini and Blatter," Pieth told the Associated Press in a telephone interview late Friday. "We desperately want to go beyond that now." Pieth suggested that Infantino disagreed over a salary offer of 2 million Swiss francs ($2.05 million) made by a three-member FIFA remuneration panel headed by Scala. "It is personal, it is very clear," Pieth said. "He wants more than the 2 million that Domenico is offering him." Publishing the presidential salary was a central pledge of the latest reform round agreed in February, in which Infantino and Scala were central players. In March, Blatter's base salary of 2,964,379 million Swiss francs ($3 million) in 2015 was disclosed by FIFA. It was later disclosed that the incoming president's salary was intended to be less, and that the new secretary general would be the highest paid employee. Asked on Friday about his salary negotiations, Infantino said it was "not yet fixed as far as I am concerned," and it was not important. Scala directly attacked Infantino's new hiring and firing powers in his resignation statement. "It will henceforth be possible for the council to impede (ethics) investigations against single members at any time, by dismissing the responsible committee members or by keeping them acquiescent through the threat of a dismissal," he said. "Thereby, those bodies are factually deprived of their independence and are in danger of becoming auxiliary agents of those whom they should actually supervise." Pieth, a criminology professor at the University of Basel in Switzerland, said the move to give Infantino new hiring and firing powers could threaten the credibility of reforms intended as a sign to American and Swiss federal prosecutors investigating corruption in world soccer that FIFA would change its culture. "They are not worth the paper they are written on," Pieth said, suggesting Scala had in recent days "not been accepting offers to step down." Gibraltar, Kosovo accepted as members of FIFA Kosovo and Gibraltar were accepted as members of FIFA Friday as soccer's governing body increased its number of affiliated football associations to 211. FIFA has already said that both teams will be able to take part in the 2018 World Cup qualifying competition which starts in September. Kosovo, which joined European soccer's governing body UEFA last week, was elected despite strong opposition from Serbia. It was not immediately clear whether Kosovar players who have already played for another national team would be allowed to switch nationalities. FIFA rules do not allow players to change allegiance but there have been calls to make an exception for Kosovo, which could have a big impact on Switzerland and Albania who both have contingents of players with Kosovar roots. FIFA rejected an application from the British territory of Gibraltar in 2014 but the Court of Arbitration for Sport (CAS) last week ordered it to reconsider and accept the request. Gibraltar has been a member of UEFA since 2013 which itself followed a 14-year battle during which it took its case to CAS. "Rare are the occasions when Gibraltar stands up and addresses the entire world," Gibraltar FA president Michael Llamas said. "It's been a very long road towards FIFA membership for us and it feels fantastic today." Gibraltar made its competitive debut in the 2016 European Championship qualifying campaign, where it lost all 10 matches, conceding 56 goals. Overall, it has played 18 matches, including friendlies, under three coaches and have achieved just one win, against Liechtenstein.
