UEFA will intervene if Cardiff win the FA Cup but are prevented from competing in the UEFA Cup, president Michel Platini has revealed.
But if they win the April 6 clash then beat either West Brom or Portsmouth in the final the Football Association insist they will not be put forward as one of England's representatives for the UEFA Cup because they come under the jurisdiction of the FA of Wales.
The Welsh governing body reserve their places for winners of their domestic competitions, leaving Cardiff potentially in limbo.
Chairman Peter Ridsdale hinted after the draw the club would challenge the FA's decision - and he would have an ally in Platini.
The former France midfielder told BBC Radio Five Live: "It's not normal that they participate in one competition and if they win they are out. That is not good.
"If England don't do something we will do something because we always respect the result."
