West Ham United have agreed a £5.5m deal to sign attacking midfielder Edimilson Fernandes from Sion, according to reports.
The 20-year-old came through the youth system at the Swiss outfit and has since made 48 first-team appearances, scoring two goals.
According to Sky Sports News, Fernandes will undergo a medical on Wednesday ahead of a move to the London Stadium.
Hammers manager Slaven Bilic has already added Havard Nordtveit, Sofiane Feghouli and Gokhan Tore to his midfield ranks this summer.
