West Ham have opened talks with Sion over their coveted midfielder Edimilson Fernandes.
The 20-year-old was labelled 'unsellable' earlier this year by Sion president Christian Constantin after Liverpool and Bordeaux expressed interest.
The Swiss U21 international is the cousin of former Manchester City midfielder Gelson Fernandes and can play in the centre or on the right-hand side.
Slaven Bilic has been looking for an energetic player who can help increase intensity in his side and sees Fernandes as one who can develop.
