Metz striker Diafra Sakho will arrive in England on Thursday in order to complete a move to West Ham, Goal understands.
The 24-year-old, who scored 20 goals in Ligue 2 last season, will move to Upton Park in a £4.5 million deal and will sign a three-year contract with Sam Allardyce’s side.
Allardyce is keen to recruit another striker following Andy Carroll’s ankle surgery, which could rule the 25-year-old out for the remainder of the year.
West Ham had considered a move for Shakhtar Donetsk striker Facundo Ferreyra before the Argentine opted to join Newcastle United on loan, while Stoke City’s Peter Crouch was also a target.
On Tuesday, Metz hit out at West Ham over their conduct during negotiations for Sakho, claiming that the Premier League club had changed the terms of the deal in the final stages of talks.
Metz, who are now in Ligue 1 after winning the French second division last term, also threatened West Ham with legal action as Sakho had travelled to England on Saturday and subsequently missed their season opener against Lille.
West Ham are expected to complete the transfer for Sakho before the weekend, although the forward’s registration is unlikely to be completed in time for him to feature against Tottenham on Saturday.
