West Ham have made a move for Celtic midfielder Olivier Ntcham.

Foot Mercato says the 23-year-old midfielder is in advanced negotiations with West Ham about a late winter market move.

Ntcham is tied to Celtic until 2022 and has impressed this season, scoring five goals and delivering four assists in 31 games.

A deal with West Ham would represent a return to England for Ntcham, having come through the academy at Manchester City.

An initial loan arrangement is favoured by the Hammers.
