The Hammers have placed a €3.5m offer for the Ivorian.
West Ham United have clearly not finished their summer spending just yet as Lille accept a €3.5m bid from the Hammers for ex-Chelsea attacker Salomon Kalou, reports French publication L’Equipe.
The bid from the east London club is said to be €500,000 more than the Ligue 1 club wanted for Kalou and with Lille in financial difficulties, it looks like a good deal for all involved.
The 27-year-old will now go into negotiations with the Irons over the move, with the Ivory Coast international having already turned down a return to the Premier League this transfer window with West Bromwich Albion.
Kalou has only been playing in France for one season following a transfer from Chelsea, having spent six years at Stamford Bridge and winning the Premier League, FA Cup four times and the Champions League.
Now the African wants to return to England and with 14 league goals last year in 28 matches, West Ham are orchestrating something of a steal to snap up the forward for so little.
So far since the end of the 2012/13 season the club have brought in four new players at Upton Park, with the £15m spent on Andy Carroll the most expensive deal so far.
Razvan Rat and Adrian have also arrived on free transfers from Shakhtar Donetsk and Real Betis respectively, but manager Sam Allardyce is still keen to improve the forward line.
Carlton Cole has left the Hammers to leave Ricardo Vaz Te and Modibo Maiga as the only support for Carroll up-front.
