West Ham are considering a deal for Saint-Etienne center-back Wesley Fofana.
The Hammers have reportedly made an initial bid of £ 23million, which could reach £ 33million with add-ons.
David Moyes is in desperate need of defensive reinforcements before the transfer window closes.
West Ham saw three offers turned down by Burnley for England international James Tarkowski and have now turned their attention elsewhere.
In an exclusive interview with talkSPORT, Hammers co-owner David Sullivan admitted he was “ feeling depressed ” by the club’s lack of transfer activity.
Sullivan has claimed he may not be able to sign more players this summer, due to the difficulty in achieving the goals Moyes wants.
But West Ham is still trying to make deals and has now turned its attention to Fofana.
However, they aren’t the only club interested in Fofana, with Leicester also eyeing the 19-year-old.
The Saint-Étienne defender has expressed his willingness to leave the Ligue 1 club this summer.
He even accused the actions of some fans of forcing him to walk away.
He told L’Equipe: “As soon as we knew I was wondering about my future, people got excited on their own when I hadn’t said anything.
“It wasn’t like they said I would move to Lyon. Calling myself a “mercenary”, “traitor” or “f *****” hurt me.
“But the fans of St Etienne who insulted my mother and my little sister, it touches me a lot. I am disgusted. Some of them went even further than that.
“I have received many offers. It is normal to have them checked by my agents. They didn’t agree with me wanting to talk (like that). But what just happened fueled something in me. My decision is made: I accept an offer. “
Asked about Leicester’s possible offer, Fofana said: “I’ve always dreamed of playing in England.”
