West Ham are set to sign left-back Emerson Palmieri from Chelsea in a deal worth £15m.
The 28-year-old Italy international spent last season on loan at Lyon and has struggled to become a regular at Stamford Bridge since his 2018 move from Roma.
Emerson is set to complete a medical on Tuesday before the move across London is confirmed.
David Moyes’ side are currently bottom of the Premier League with no points from three matches.
The Hammers’ biggest signings have been striker Gianluca Scamacca from Sassuolo for £30m, defender Nayef Aguerd from Rennes for £30m and forward Maxwel Cornet from Burnley for £17.5m.
They have also signed midfielder Flynn Downes from Swansea for £12m, and defender Thilo Kehrer and goalkeeper Alphonse Areola, each for a reported £10m from Paris St-Germain.
