West Brom have confirmed they have reached an agreement with NEC Nijmegen for Jonas Olsson's services.
The Baggies have agreed to pay the Eredivise club £800,000 for the 25-year-old defender, who is a former Sweden Under-21 international.
Olsson has agreed personal terms with Tony Mowbray's side and will finalise his Hawthorns transfer upon completing a medical over the weekend.
The left-sided stopper has been playing for NEC for the past three seasons following a move from home-town club Landskrona in 2005.
Olsson will become the club's sixth fresh face to arrive this summer following the captures of Borja Valero, Abdoulaye Meite, Marek Cech, Scott Carson and Gianni Zuiverloon.
