Breakaway European Super League founder and Juventus chairman Andrea Agnelli said on Wednesday that the league can no longer go ahead after six English clubs withdrew.

Asked whether the project could still happen after the exits, Agnelli told Reuters: "To be frank and honest no, evidently that is not the case."

Twelve of Europe's leading football clubs -- Juve, Inter Milan, AC Milan, Real Madrid, Barcelona, Atletico Madrid, Manchester United, Manchester City, Liverpool, Chelsea, Tottenham Hotspur and Arsenal -- announced a breakaway league on Sunday but after 48 hours of intense criticism and political opposition, the six English clubs backed out on Tuesday.

Agnelli said he remained convinced that European football needed change and he had no regrets about the way the breakaway attempt was made.

"I remain convinced of the beauty of that project," Agnelli said, stating it would have created the best competition in the world.

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