Crystal Palace are poised to acquire winger Ismaila Sarr from Marseille for approximately £12.5m.
The 26-year-old is set to sign a five-year contract with the club.
Sarr moved to Marseille from Watford in July of the previous year for an undisclosed fee.
During his time at Watford, he scored 34 goals in 131 appearances, and last season, he notched five goals and six assists for Marseille across all competitions.
The Senegalese international, who has 13 goals in 64 caps for his country, won the Africa Cup of Nations in 2021 and has competed in two World Cups.
Marseille, who recently appointed former Brighton manager Roberto de Zerbi, have brought in Manchester United forward Mason Greenwood and are looking to recoup some funds.
Palace, having received £50m from Michael Olise’s transfer to Bayern Munich, have been active in the transfer market this summer.
In addition to Sarr, they have signed Japanese midfielder Daichi Kamada from Lazio on a free transfer and Moroccan defender Chadi Riad from Real Betis in a £14m deal.
