What are the rules?published at 12:52 British Summer Time

The rules of European football's governing body state that clubs owned, to a certain threshold of influence, by the same person or entity cannot compete in the same European competition.
Uefa's rules set a deadline of 1 March 2025 to show proof of mutli-club ownership restructuring - a deadline Palace missed.
But the South London team argued Textor does not hold any decisive influence at the club, but Uefa did not accept the Premier League club's defence.
Uefa's regulations around multi-club ownership and European competitions are in place to prevent collusion.
In the governing body's rulebook, a club is required to prove they are not "simultaneously involved in any capacity whatsoever in the management, administration, and/or sporting performance of more than one club participating in a Uefa club competition".
Textor's Eagle Football owns a 43% stake in Palace and 77% stake in Lyon, but Premier League side argued they are an entity that operates entirely independently.
