Welcome to Barcelonaton FC
Legally I dont think they can stop them playing in it, if I was the premier league I would schedule their league games when they are due to play in Europe.
They can't stop them playing in it.
However, what they have done is ruled themselves and the players out of recognised competitions such as the champions league, Europa, super cup, euros and world cup ran by the organisations and unions they're supposed to be a part off (which they also quit last night).
The PL rules state that teams aren't allowed to play in non-recognised leagues or competitions.
So until a governing body sanctions this league...they're all playing a dangerous game domestically.
