West Ham are preparing a bid for the Marseille winger Georges-Kévin N’Koudou but could face competition from Liverpool and Manchester United for the France Under-21 player.

All three clubs have scouted the former Nantes player extensively this season, with representatives present at last month’s French Cup final when Marseille were beaten by Paris Saint-Germain at the Stade de France. West Ham are understood to be ready to offer around £10m for the 21-year-old, although it is likely that the French club’s asking price may be significantly higher,

However, with the chair Margarita Louis-Dreyfus having put Marseille up for sale in April, they may be forced to accept a lower fee.

N’Koudou moved to the Stade Vélodrome last summer from Nantes for £1m and scored 11 goals in all competitions in his debut season for Marseille.
