West Ham have completed the signing of Adama Traore from Fulham, reuniting the winger with head coach Nuno Espirito Santo.
Sky Sports News understands the fee will rise from an initial £1m to £2m.
The 30-year-old Spain international spent three seasons alongside Nuno at Wolves between 2018 and 2021, arriving at the London Stadium aiming to lift the Hammers out of the Premier League relegation zone. Traore is expected to be available for his Chelsea debut, which will be broadcast live on Sky Sports on Saturday.
“I’m very happy to be here and I’m very happy to help the team as much as I can and show my quality,” said Traore, who came through Barcelona’s academy and went on to play for Aston Villa, Middlesbrough, Wolves and Fulham, making 262 Premier League appearances, scoring 14 goals and providing 25 assists.
Commenting on their reunion, Nuno said: “He’s someone I know well from our time together at Wolves and I’m looking forward to working together again.”
“Adamah is someone who knows the Premier League well and his unique qualities as a player will help us from now until the end of the season.
“He will give us different options in attack and is very willing to fight for us and is ready to bring energy, dedication and determination to our challenge.”
Traore has started one Premier League game and made 14 substitute appearances for Fulham this season, with Marco Silva’s side close to agreeing an agreement with Man City for Oscar Bobb.
Ward Prowse receives Burnley medical treatment
Meanwhile, West Ham midfielder James Ward-Prowse is currently undergoing a medical in preparation for a loan move to Burnley until the end of the season.
Negotiations took place earlier, but no resolution was achieved. Burnley appeared to walk away, but talks resumed on Tuesday.
Ward-Prowse could be the first signing for the promoted side as they fight to stay in the Premier League.
West Ham have told Ward-Prowse, 31, that he is not part of their plans.
Ward-Prowse did not feature under Nuno but was on the bench in Saturday’s 3-1 win over Sunderland.
