The 24-year-old made 30 Serie A appearances for the Italian outfit last season, notching up one goals and two assists whilst averaging 1.9 tackles and 1.6 interceptions per match.
He primarily operates at left-back but can also play in midfield and boasts experience on the international stage, with 16 caps for Morocco.
West Ham were linked with the 5 foot 9 ace by Goal earlier this summer as a potential replacement for the injured Aaron Cresswell.
The Irons have already snapped up one stand-in in the form of Arthur Masuaku but it appears they’re still targeting Lazaar for a summer transfer.
Indeed, London Evening Standard claim the East London side are very close to signing the African defender, who is available on the cheap due to his contract expiring at the end of next season.
Palermo reportedly want just £2.5million for Lazaar and West Ham look set to pay up.
