The Irons are today being reported as having agreed a £5.5million deal to sign FC Sion midfielder Edimilson Fernandes.
And according to The Guardian the Swiss midfielder, 20, is set to travel to London on Wednesday for a medical.
Fernandes made 26 appearances in the Swiss Super League last season, scoring one goal.
He also played against Liverpool twice in the Europa League last term.
Speculation is now set to start that the Hammers are ready to part with Pedro Obiang who has been unable to hold down a regular place in the team.
