Cardiff's 3-0 defeat by Crystal Palace in early April should not be allowed to stand, the Welsh club has said in a five-page letter seen by the BBC.
The document, sent by club lawyers to the Premier League, alleges Palace boss Tony Pulis knew sporting director Iain Moody was trying to obtain Cardiff's starting line-up before the game.
The club claims it has proof Moody succeeded and says this breaches league rules. Pulis declined to comment when contacted by the BBC, although Palace previously denied the claims.
Cardiff states that clubs should act in good faith to one another and calls into serious question the integrity of the match.
The club says Crystal Palace cheated and wants the Premier League to take serious action.
Now for me, I can't see this has legs at all. Yep, it was wrong and yes Palace will be punished, but simply knowing a team line up before a game? Can't see how that could possibly warrant a game being replayed.
Here's the Cardiff line up the game before the Palace match;
Taking points from a team is possible, but giving a team points would never happen. It wouldn't surprise me if the FA did nothing until the end of the season and if they chose to punish Palace with a points deduction it would be done in a way that didn't affect the league table.
While Cardiff player Aron Gunnarsson is named as the source of the leak in the Moody text, he has denied to the club that he was behind it. His agent, Jerry de Koning, has also denied leaking the team.
