Juventus chairman Andrea Agnelli says the European Super League is dead after six English clubs withdrew from the competition.

The vice-president of the proposed breakaway competition has admitted this morning that it's impossible to proceed without the Premier League sides.

Chelsea, Spurs, Arsenal, Manchester City, Liverpool and Manchester United backed out of the competition last night following backlash from supporters and the threat of sanctions from UEFA.

"To be frank and honest no, evidently that is not the case," the Juventus chief told Reuters when asked if the tournament could ahead without the English teams.

"I mean, I don't think that that project is now still up and running."

Agnelli says he remains convinced of the "beauty of the project" and believes it could have been the best club football competition in the world.

Earlier, Liverpool owner John W Henry apologised to the club's fans over their controversial plans to play in the Super League.

Henry has taken responsibility for the 'unnecessary negativity' of the past 48 hours and says supporters are crucial to the club.

"I want to apologise to all the fans and supporters of Liverpool Football Club for the disruption I caused over the last 48 hours," he said in an address directly to fans.

"It goes without saying but should be said, the project put forward was never going to stand without the support of the fans.

"No-one ever thought differently in England. Over these 48 hours you were very clear that it would not stand. We heard you. I heard you.
