West Ham are continuing discussions over personal terms after agreeing a £30.5million fee with Sassuolo for Gianluca Scamacca.
The Italy striker, 23, is prepared to become West Ham's fourth signing of the summer if agreement can be reached.
Manager David Moyes was keen to move quickly as Chelsea are reluctant to let Armando Broja out just yet who is receiving treatment for an injured ankle.
