West Ham are discussing personal terms with Said Benrahma over his proposed £30m transfer from Brentford.
The 25-year-old will take a medical in next 24 hours if and when personal terms are agreed.
West Ham are increasingly hopeful Benrahma can complete his move ahead of Friday’s deadline having agreed a deal with Brentford earlier this week.
Discussions between West Ham and Benrahma are over a five-year deal.
Earlier on Wednesday, Benrahma held a meeting with Brentford officials to try and resolve a dispute over a payment he believes he is owed.
Benrahma scored 17 goals in 46 appearances for Brentford last season as they reached the Championship play-off final before Thomas Frank’s side were beaten by Fulham in extra-time at Wembley.
Meanwhile, West Ham remain interested in Bournemouth forward Joshua King despite having had a £13m bid for him rejected at the weekend, with the Championship club valuing the Norway international at around £18m.
