Arsenal, Chelsea, Liverpool, Manchester City, Manchester United and Tottenham are among 12 clubs who have agreed to join a new European Super League (ESL).
In a seismic move for European football, the Premier League clubs will join AC Milan, Atletico Madrid, Barcelona, Inter Milan, Juventus and Real Madrid.
The ESL said the founding clubs had agreed to establish a “new midweek competition” with teams continuing to “compete in their respective national leagues”.
It says the inaugural season “is intended to commence as soon as practicable” and “anticipated that a further three clubs will join” the breakaway.
The ESL says it also plans to launch a women’s competition as soon as possible after the men’s tournament starts.
UK Prime Minister Boris Johnson, Uefa and the Premier League condemned the move to launch a European Super League when news of it broke on Sunday.
World governing body Fifa has previously said it would not recognise such a competition and any players involved in it could be denied the chance to play at a World Cup.
Uefa, Europe’s governing body, reiterated this warning on Sunday when it said players involved would be banned from all other competitions at domestic, European or world level and could be prevented from representing their national teams.
After the Super League was announced, Fifa expressed its “disapproval” of the proposed competition and called on “all parties involved in heated discussions to engage in calm, constructive and balanced dialogue for the good of the game”.
In a statement, the ESL said: “Going forward, the founding clubs look forward to holding discussions with Uefa and Fifa to work together in partnership to deliver the best outcomes for the new league and for football as a whole.”
