UEFA president Aleksander Ceferin has spoken about recent talks with Manchester United executive vice-chairman Ed Woodward and the Glazer family who own the club.
United were among 12 clubs that attempted to form a breakaway European Super League earlier in the year.
Their plans failed miserably, as fan reactions meant almost all of the clubs withdrew from the ESL within days.
Ceferin now says that Woodward claimed he was unaware of the Super League plans.
"He said he didn't know that it [ESL] was happening, But, I don't know," Ceferin told The Telegraph.
"I don't want to accuse him or not. I have not said anything about him to anyone else.
"I just said he called me and said the reforms [of the Champions League] are good. Maybe he was honest back then, I don't know. But he [later] wanted to explain that he didn't know it [the ESL] was ever happening. That's as much as I know."
He added: "I spoke with Joel Glazer and he was honest when he said 'look we made a mistake. We know we have to suffer sanctions and we will never do it again'. I believe him."
