Premier League chief executive Richard Masters has accused embattled FIFA president Gianni Infantino of pressing the "self-destruct button" over failed plans to sell stakes in the World Cup.
Infantino is fighting to stay in his job following huge backlash to his intention to sell a minority stake in FIFA tournaments to private investors.

UEFA has become his main detractor, with the English Football Association withdrawing its support for Infantino.
"This is a problem of FIFA's making," Masters told BBC Sport.
"This is a self-inflicted wound. The organisation has pressed the self-destruct button, and the consequences of that flow now into the solutions that need to be found.
"I don't think FIFA should be ever contemplating selling off a stake in the World Cup.

"I think it's a bad idea, and the FA have taken the right position regards to Gianni [Infantino]."
On a potential rival to Infantino's re-election next year, Masters added: "I think an emerging unity candidate should have on his or her agenda reform of FIFA, and perhaps even reform of the president's role and how it interacts with those things."
Earlier, Israel became the latest UEFA member association to withdraw its support for Infantino, while UEFA vice-president Laura McAllister said FIFA's decision to dismiss senior executive Kevin Lamour sends a "deeply troubling message to all of us seeking change".
FIFA confirmed Lamour's departure as chief operating officer on Monday evening, just over two weeks after he released a statement to the Associated Press saying the FIFA administration had been "deceived" by Infantino over his plan.
Lamour's statement on July 31, along with the resignation of senior adviser Carlos Cordeiro earlier the same day, heaped further pressure on Infantino, with Lamour describing the private investor plan as "the project of one person."
McAllister, a former Wales captain who worked with Lamour at European football's governing body when he was its deputy general secretary, has criticised his sacking.
