These regulations state that no individual can have control or influence over more than one club participating in a European competition. American businessman Simon Textor owns a significant stake in Crystal Palace and a controlling share in Lyon, another French club. If Paris Saint-Germain wins the Coupe de France, Lyon would qualify for the Europa League, and Crystal Palace might be relegated to the Conference League.

This would be due to the fact that the cup winners' spot in France would drop a place in the league, as the Ligue 1 champions have already qualified for the Champions League. UEFA's rules specify that no individual or entity can have control or influence over more than one club participating in a UEFA competition.

According to the regulations, control or influence can be defined as holding a majority of voting rights, appointing or removing a majority of the club's administrative body, or having a significant influence in the club's decision-making process. However, it is reported that Textor only has a 25% voting right in Crystal Palace, the same as other co-owners Steve Parish, Josh Harris, and David Blitzer. Therefore, the club is not run by Textor, which might help them avoid relegation to the Conference League.

This situation is different from that of Nottingham Forest, where the owner had to place the club in a blind trust due to his ownership of both Forest and Olympiacos, who will also be in Europe next season.
