Crystal Palace boss Oliver Glasner is "positive" the club will be successful in their appeal against demotion from the Europa League to the Conference League.
The Eagles were punished for breaching multi-club ownership rules as American businessman John Textor owns a stake in the club and is the majority owner of French side Lyon, who have also qualified for the Europa League.
In July, Palace submitted an appeal to the Court of Arbitration for Sport against Uefa, which issued the punishment, as well as Lyon and Nottingham Forest.
Forest, who finished seventh in the Premier League last season, will replace FA Cup winners Palace in the Europa League if the punishment is upheld.
