According to French newspaper L'Equipe, West Ham are chasing Caen midfielder N'Golo Kante - and could make a bid in the coming days.
The Hammers have already strengthened heavily this summer under new manager Slaven Bilic, with Darren Randolph, Carl Jenkinson, Angelo Ogbonna, Pedro Obiang, Dimitri Payet and Manuel Lanzini all penning deals at Upton Park.
However, Bilic still needs more reinforcements ahead of the new Premier League season, and midfield could still be a concern given that West Ham have yet to secure a deal to bring last season's loanee Alex Song back to the club for a second spell.
Now, French newspaper L'Equipe report that Caen midfielder N'Golo Kante is a target for the Hammers after an impressive season in French football.
The diminutive midfielder, 24, has earned a reputation for being an effective box-to-box player during his two-year stay at Caen, but an exit now looks likely before the transfer deadline.
L'Equipe suggest that West Ham are very keen on Kante, and could even lodge a bid for the player in the coming days as they look to win the race for Kante's signature.
Kante or Song?
West Ham are no doubt still pushing to bring Barcelona misfit Song back to Upton Park, with the 27-year-old performing well over the course of last season.
However, Song will be far more expensive than Kante, and West Ham may prefer to take a gamble on the younger Kante, who is coming off the strongest season of his career so far.
Song's physicality and ability to sit in front of the back four could be more appealing than signing another box-to-box midfielder having already landed Obiang earlier this summer - so it may simply come down to how Bilic intends to use a new midfield signing.
