West Ham United are prepared to lure away Steven Caulker from Queens Park Rangers if the Loftus Road outfit cannot secure Premier League football next season, Mirror reports.
The 23-year-old was a top defensive target for a number a clubs when his Cardiff side was relegated the previous season, with Arsenal, Everton, and Liverpool some of the teams reported to be interested.
Sam Allardyce was also said to have made an attempt to sign Caulker during the January deadline day, but QPR owner Tony Fernandes rejected the offer.
The Hammers are already considering moves for a new centre-back as they prepare to lose Winston Reid in the summer, with his contract set to expire.
However, they are also eyeing Genk defender Kara Mbodj as another possible candidate capable of filling the void once the New Zealand international leaves Upton Park.
QPR are currently struggling in 19th place in the league and are now without a manager after Harry Redknapp decided to leave the club following their 3-1 loss to Stoke City.
