Eagles want to sign England international Caulker and one of his former Tottenham teammates.
Crystal Palace manager Tony Pulis is poised to lodge an £8m bid for Cardiff City defender Steven Caulker, according to The Mirror.
The 22-year-old centre-back looks set to leave the Bluebirds after suffering relegation in his first season with the South Wales club.
It is believed that he has a release clause in his current contract, which Palace’s £8m offer would trigger.
Liverpool and Arsenal have also been linked with interest in Caulker, who made 29 first-team appearances for Tottenham Hotspur between 2010 and 2013.
Pulis is apparently keen on signing Caulker’s former Spurs teammate Jake Livermore too.
Livermore spent this season on loan at Hull City, but the Tigers are yet to agree a transfer fee for a permanent deal.
Spurs are said to want £6.5m for the 24-year-old – a figure that Palace are reportedly willing to pay.
Livermore and Caulker have both represented England once at senior international level.
Caulker was one of Cardiff’s best players this season. He started all 38 of the club’s Premier League matches, scoring five goals.
At the back, he made 44 tackles, 47 interceptions, 59 blocks and 327 clearances.
Midfielder Livermore made 36 Premier League appearances for Hull, scoring three goals and providing four assists.
