Crystal Palace have reportedly contacted Cardiff City in a bid to sign defender Steven Caulker.
The 22-year-old has been linked with moves to several Premier League sides following Cardiff City's relegation from the top flight, including Arsenal, Tottenham Hotspur and Liverpool.
However, the Daily Mail now reports that Tony Pulis is interested in bringing the defender to Selhurst Park, and that the club have already expressed a formal interest in Caulker to Cardiff.
Caulker is understood to have an £8m release clause in his contract with the Bluebirds.
