US attorney general Loretta Lynch declined to say if Blatter is a target.

The reports come as America’s top law enforcement official visited Switzerland, where Federation Internationale de Football Association is based, and said the global probe into soccer corruption “has expanded”.

“The scope of our investigation is not limited, and we are following the evidence where it leads”, she continued.

Lynch expects the investigation to wide, she stated: “We do anticipate pursuing additional changes against individuals and entities”.

Swiss federal agencies have seized properties in the Swiss Alps and seized evidence during house searches in western Switzerland, Lauber said.

In May the USA indicted nine football officials and five sports marketing executives, charging them with racketeering, money laundering and wire fraud on suspicions they orchestrated multi-million dollar bribery schemes over 24 years.

Swiss attorney general Michael Lauber is also due to give details on the separate investigation into the 2018 and 2022 World Cup votes.

Mark Pieth, a Swiss professor of criminal law and FIFA’s former anti-corruption adviser, said there was “prima facie” evidence about the sale which saw Warner make a profit of at least £11million.

Prince Ali suggested Blatter should take responsibility for the organisation’s failings, although the Swiss national has denied any wrongdoing.

Much of FIFA’s contracts and finances during Blatter’s 17-year presidency now seem open to investigation. CFU not only failed to fulfil its payment commitments but made several breaches to the contract. “No corrupt organization is beyond its reach”.

Lynch did not comment Monday on whether Blatter is targeted in her case, or if he faced arrest by traveling to a country which has an extradition treaty with the United States.

FIFA’s president for almost two decades, Sepp Blatter, won re-election just two days after the indictment was unveiled in May.

According to court documents in the Cayman Islands, Jeffrey Webb – Warner’s successor as president of the CONCACAF confederation – was a director of JDI at the time of the deal. His second-in-command was Chuck Blazer, an American soccer official who lived in outrageous luxury in the Trump Tower.

In May, the U.S. justice department announced indictments against 18 people on football-related corruption charges – four have pleaded guilty to charges.
