West Ham United are believed to be targeting a summer bid for Chelsea forward Salomon Kalou.
The Ivorian's future at Stamford Bridge is in doubt as he nears the end of his current deal, which expires at the end of the season.
While former Blues boss Andre Villas-Boas was believed to be hatching out a fresh contract for the 26-year-old, it is thought that the Hammers are ready to pounce, according to the Express.
The East London side are likely to get promoted to the Premier League at the end of the season as they sit just three points adrift of Championship leaders Southampton.
It is believed that manager Sam Allardyce is eager for Kalou to lead the Hammers in the top flight.
