West Brom have officially confirmed the signing of midfielder Semi Ajayi from League One side Rotherham. 

The club have revealed that Ajayi has put pen to paper on a four-year contract at West Brom, becoming the third arrival of the summer.

Filip Krovinovic has joined on loan from Portuguese giants Benfica, whilst Kenneth Zohore completed his permanent move from Cardiff earlier this week.

Ajayi caught the eye for Rotherham in the Championship last season, despite their relegation back down to League One.

He started his career, and last season, as a central defender, but impressed after moving into a holding midfield role under Paul Warne at Rotherham. 

The Nigerian international scored seven goals for Rotherham in the Championship last season and will now be looking to progress further under Slaven Bilic at The Hawthorns next season. 

West Brom finished 4th in the Championship last term and will be hoping to push on and achieve promotion back to the Premier League with Bilic.
