Atalanta have told West Ham it will cost them £22m to sign Bryan Cristante.
The midfielder has shone in Italy this season while on loan from Portuguese giants Benfica.
Atalanta are now set to take up their option to sign the 22-year-old permanently, before instantly selling him on for profit.
The Italian club can land Cristante from Benfica for £4.5m but, according to Premium Sport, they will then ask interested clubs to part with £22m.
West Ham are one of those chasing the Italian, while he has more recently been linked with Manchester United.
Cristante is also on the radar of clubs in Serie A, including Juventus and Inter Milan.
