Infantino distances himself from Euro PL proposals
Infantino says he is not interested in a European Premier League.
Sky News has learned Liverpool and Manchester United have held discussions about a bombshell plot involving Europe's biggest football clubs to join a new FIFA-backed tournament that would reshape the sport's global landscape.
More than a dozen teams from England, France, Germany, Italy and Spain are in negotiations about becoming founder members of the competition - with Spurs, part of the Premier League's 'big six' clubs, included in those conversations.
"As FIFA president, I'm interested in the Club World Cup, not the Super League," said Infantino.
"For me, it's not about Bayern Munich against Liverpool, but Bayern against Boca Juniors."
Infantino impressed by Qatar 2022 preparations
Qatar's preparations for hosting the 2022 World Cup have progressed despite the coronavirus pandemic, Infantino said on Wednesday, adding that he was speechless after visiting the Al Bayt stadium.
The 50-year-old visited the 60,000-capacity stadium, designed to resemble a traditional Arab tent, on a flying visit to Qatar and played in a seven-a-side match before meeting local organisers.
"Al Bayt Stadium is incredible: a true football stadium," Infantino said in a FIFA statement. "It has a real football feel and a local touch. The tented shape makes it truly unique, and the Arabic patterns in the roof are just beautiful. I am speechless."
