The New York Times has reported Chelsea and West Ham have agreed to buy the services of West Ham United players, including former striker Diafra Sakho.
The deal would be worth around $20 million and could be completed in the coming weeks, according to the Times.
The Times said the sale would see Sakho become Chelsea’s second biggest signing, after former Chelsea striker Fabio Capello, who was in England for the first time when Chelsea signed him.
Chelsea’s transfer strategy was also said to include acquiring striker Yaya Touré, who joined the London club in 2012.
The deal will reportedly see the signing of Diego Costa, a club record signing, along with the signing from Monaco of former Arsenal forward Alexandre Lacazette, who has made just one appearance for the Gunners.
The sale is the latest of several moves by Chelsea to bring in players for their youth academy.
Last summer, they signed winger Michael Essien, who had scored just three goals in 27 appearances in the Premier League this season.
