West Ham have put in a bid to sign Sunderland midfielder Didier Ndong, with talks between the two clubs ongoing.
Ndong has been tipped to leave the Stadium of Light this summer following Sunderland's relegation from the Premier League and the midfielder is of interest to Ligue 1 giants Lyon.
But West Ham are putting in the hard yards over a deal at present and, according to French radio station RMC, have made a bid for Ndong.
It is claimed the two English clubs are locked in talks over a move which would see the Gabon international play his football at the London Stadium this season.
Ndong was snapped up by Sunderland from French side Lorient and his stock remains high in Ligue 1.

Lyon continue to be keen on a player who is just 23 years old.
Ndong joined Sunderland in the winter transfer window in 2015 and put pen to paper on a four-and-a-half-year contract with the Black Cats.
He cost Sunderland a substantial £13.6m to sign and it is unclear what level West Ham's offer is.
