UEFA president Aleksander Ceferin insisted players who represent clubs competing in the European Super League will be banned from international competitions despite pre-emptive legal moves by the new organisation.
Six Premier League sides – Arsenal, Chelsea, Liverpool, Manchester City, Manchester United and Tottenham – are part of an initial group of 12 clubs seeking to establish a new 20-team continental competition "as soon as practicable".
If the plans succeed it would devastate existing European club competitions and in particular the Champions League. A joint statement including UEFA and the English, Italian and Spanish leagues on Sunday said it would consider "all measures, both judicial and sporting" to prevent the competition going ahead.
The Premier League released a statement condemning the proposals on Sunday.
BT Sport, UK broadcaster of the Premier League and Champions League, said in a statement: "BT recognises the concerns raised by many of football's leading voices and fans and believes the formation of a European Super League could have a damaging effect to the long term health of football in this country.
"As a sport broadcaster showing Premier League, UEFA club football and National League football as well as being lead partner for all the home nations football teams, we strongly believe that football makes a significant positive contribution to people's lives at every level, and this needs to be protected."
