Cardiff City: Crystal Palace result should not stand

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.
The Premier League has confirmed it will investigate.
