Crystal Palace are likely to acquire winger Ismaila Sarr from Marseille for a sum of around £12.5 million.
The 26-year-old is likely to sign a five-year contract with Selhurst Park.
Sarr joined Marseille from Watford in July of last year for an unknown amount.
During his tenure at Watford, the winger scored 34 goals in 131 games and finished last season with five goals and six assists in all competitions for Marseille.
Sarr, who has 13 goals in 64 Senegal appearances, won the Africa Cup of Nations in 2021 and competed in two World Cups.
Marseille, who appointed former Brighton manager Roberto de Zerbi earlier this summer, signed Manchester United forward Mason Greenwood earlier this month and have been looking to recoup funds.
Palace have been searching for a replacement for Michael Olise since the Frenchman joined Bayern Munich.
Palace banked £50m from Olise’s departure and the club have been active in the market so far this summer.
Daichi Kamada, the 27-year-old Japanese midfielder, has joined from Lazio on a free transfer while Chadi Riad, who has three-caps for Morocco, has joined in a £14m deal from Real Betis.
