The Toffees are said to be in the market for a new midfielder following Ross Barkley’s injury blow, with the Senegal star top of their list.
It’s understood that a deal was close to completion last week, and that the rangy former Wigan man had already bid farewell to his team-mates at Upton Park before the agreement stalled over personal terms.
Despite the hiccup, it’s expected that Everton will get the switch finalised, with Diame himself desperate to prove himself in the upper echelons of the Premier League.
The Merseysiders will only have to pay £3.5m due to a much publicised release clause in the 27-year-old’s contract.
West Ham have been attempting to improve their African star’s deal to keep him in east London, but the player himself is against doing so amid concerns that the Irons cannot match his level of ambition.
Liverpool, Arsenal and Tottenham have all been linked with Diame in the past.
