Crystal Palace have grown increasingly exasperated at the delay in Uefa's ruling over their Europa League future and feel they are being unfairly treated, BBC Sport understands.
Well-placed sources have indicated the south London club will also almost certainly launch a legal fight against any decision to ban them from the competition next season.
There are frustrations at Selhurst Park that the delay in ruling whether Palace have breached multi-club ownership (MCO) rules in relation to American businessman John Textor's involvement at Palace and Lyon is aiding the French club's fight to stay in next season's Europa League at the expense of the Eagles.
