Mbaye Diagne is undergoing a medical in Turkey ahead of his loan move to West Brom from Galatasaray.
The 29-year-old striker, who has scored 11 goals in 19 appearances in all competitions this season, is set to join the Premier League club on an initial loan with an option to buy.
West Brom have been given permission to speak with the Senegal international and the club are currently making arrangements to fly him into the UK as soon as possible.
Bringing a striker to The Hawthorns has been top of Sam Allardyce’s priorities since he was appointed West Brom manager in mid-December.
The club has also shown interest in Crystal Palace forward Christian Benteke but the Belgium international is expected to remain at Selhurst Park.
The Baggies have also made an enquiry to Manchester United about the possibility of a loan deal for midfielder Jesse Lingard.
The potential loan fee for Lingard and level of his wages would be an issue for West Brom unless United are prepared to heavily subsidise the deal, however.
United are unlikely to do so and are in talks with West Ham, with Lingard understood to be willing to join the London club.
Who is Mbaye Diagne?
Diagne began his career in the Italian lower leagues and was spotted and signed by Antonio Conte for Serie A champions Juventus as a 21-year-old in 2013.
However, he was unable to make his name there and moved to China with Tianjin TEDA three years later.
After 15 goals in the Chinese Super League, he returned to Europe and signed for Turkish side Kasimpasa, where he scored 32 league goals across two seasons and was then snapped up by Galatasaray in 2019.
For them, he has been playing as a lone centre-forward and is a sizeable presence up front, a very good finisher who has also shown an ability to drop deeper and link up play.
According to Wyscout data, he has the best expected goals (10.3) and best expected goals and assists (10.94) rating in Turkey this season.
