West Ham are closing on the £25million signing of Rennes defender Nayef Aguerd.
The 26-year-old centre-back has been a long-time target of manager David Moyes and West Ham have increased their initial offer to get the deal for the Morocco international over the line.
Aguerd's arrival could signal the departure of Issa Diop who has a year left on contract and struggled for form at times last season.
Kurt Zouma also had a couple of spells on the sidelines last season while Craig Dawson also struggled with fitness.
