The uncertainty over Palace’s European spot for next season stems from a perceived breach of Uefa’s multi-club ownership rules.

Eagle Football Holdings – owned by American businessman John Textor – is at the centre of the case.

The company currently owns stakes in Palace and Lyon, with Uefa rules stating clubs cannot compete in the same European competition if they are owned to a certain threshold of influence by the same person or entity.

FA Cup winners Palace have argued Textor does not hold any decisive influence, but Uefa are yet to rule over whether they accept the Premier League side’s defence.

Had Lyon’s relegation been upheld, they had agreed with Uefa to be excluded from the Europa League, clearing the way for Palace to play in the competition.
