Manchester United reportedly had scouts at Marseille's Ligue 1 clash against Lyon on Sunday night, with Georges-Kevin N'Koudou the subject of the Premier League side's interest.
The 20-year-old spent two years with Paris Saint-Germain during his youth career, but stepped into the senior game with Nantes in 2015.
The France-born attacker joined Marseille at the start of this season, signing a five-year deal with the club, and has scored eight times in 20 appearances during the 2015-16 campaign.
According to The Guardian, N'Koudou's performances in recent weeks have alerted Man United, who are believed to be in the market for fresh attacking talent this month.
Liverpool and West Ham United have also both reportedly watched the youngster this season.
