West Brom have agreed a £1.3million deal for Rotherham United defender Semi Ajayi.
The 25-year-old former Arsenal junior was relegated with Rotherham last season but impressed enough to earn supporters player of the year award.
He can also play in midfield and is a Nigeria international.
Albion are close to finalising terms with striker Kenneth Zohore from Cardiff City and want to add a right back.
