One of the FIFA members appointed to head the world body's clean-up drive has admitted questions still remain over the awarding of the 2022 World Cup to Qatar.
Theo Zwanziger, from Germany, also expressed concern that other FIFA members had been pressured to vote for Qatar by their governments rather than do what was best for football.
Zwanziger has been appointed to head one of three new task forces driving reforms of FIFA, and he said questions remained over a leaked email from FIFA general secretary Jerome Valcke in which he said Mohamed Bin Hammam "thought you can buy FIFA as they [Qatar] bought the World Cup''.
"I have not forgotten this sentence, this has to be cleared up,'' Zwanziger told the Frankfurter Allgemeine Sonntagszeitung.
"I do think that the word 'buy' does not necessarily mean that bribes to certain individuals were paid, but rather a political influence was meant.
"In my opinion that the vote for Qatar was decided by some members of the executive committee who are in a very close relationship with their governments, who pushed the political case for Qatar.''
Zwanziger said the German Chancellor had never tried to exert any pressure but he doubted that was the case in other countries.
Valcke has insisted he was not suggesting that Qatar had tried to buy votes but that "the winning bid used their financial strength to lobby for support''.
Zwanziger also expressed his determination to scrap the International FA Board (IFAB), the game's law-making body which is made up of the four British associations and FIFA.
He added: "I am convinced that things can not continue. The methods are rather like the Empire and is not a modern democracy. You propose a sensible amendment and often not even a decent answer.''
He said the DFB had proposed to experiment with sin-bins in amateur or lower league football but that it had been postponed "without explanation''. He said: "I think that's not very transparent and democratic.''
