The breakaway competition could return with a new format later this year.
UEFA president Aleksander Ceferin has claimed Manchester United and Liverpool were more “involved” in the Super League than other Premier League sides.
Super League chiefs initially launched the project in April 2021. However, the plans for a new European tournament collapsed under widespread backlash from the media and football fans.
Arsenal, Chelsea, Liverpool, Manchester City, Manchester United, and Tottenham were among the competition’s 12 founding members.
However, Ceferin says their level of involvement in the Super League plans were different.
Speaking to Gary Neville on the Overlap YouTube channel, he said: “As much as I know, unfortunately your club’s [United’s] owners were very much involved and Liverpool as well.
“I think that those two were from the English side the most involved [in the Super League].
“When I arrived in Switzerland, I got a phone call from one of the English clubs saying that we’ll have to join this project.
“They didn’t like it but didn’t want to be the only ones out. Two clubs were hesitating in England very much, they said they wanted to stay friends with us, our friends from within.
“The last to join were Chelsea and Manchester City. I’m not sure about Tottenham and Arsenal.”
