West Ham are leading the chase to land one of the most sought-after young talents in Europe - that's Lyon's 22-year old centre-back Samuel Umtiti, according to Sky sources.
The Cameroon-born defender, who's been named on Didier Deschamps 'stand-by' list for Euro 2016, helped Lyon to second place in Ligue Un, scoring once in 30 appearances.
Umtiti has previously been linked with a move to PSG, Barcelona and Spurs.
Lyon may not be keen to strengthen their biggest rivals in France - who finished 31 points ahead of them this season.
