Ismaila Sarr is on the verge of joining Crystal Palace, with the winger reportedly undergoing a medical in London, according to Fabricius Romano.
The Senegal international is expected to sign a four-year contract with the Eagles after agreeing a £12.7m (US$16.3m) deal with Marseille.
The move to Palace comes as the club look to replace star winger Michael Olise, who left for Bayern Munich earlier this month in a £50 million ($64.3 million) deal.
Sarr will become the third addition to the Palace squad this summer. The club have already secured the services of Moroccan defender Chadi Riad from Barcelona and have reunited manager Oliver Glasner with Daichi Kamada, who joined on a two-year contract following his release from Lazio.
The Eagles are pursuing an aggressive recruitment drive, led by sporting director Dougie Freedman, who recently turned down an approach from Newcastle to stay at the club.

He moved to Marseille last summer, where he scored five goals in 35 appearances during a turbulent campaign that saw the club finish eighth in Ligue 1.
