Arsenal, Tottenham and Manchester United have sent scouts to watch the son of World Cup winner Lilian Thuram, according to The Sun.
Marcus Thuram has scored 10 goals in 17 games for Guingamp this season.
The 21-year-old striker recently scored the winner as his side shocked Paris Saint-Germain in the French League Cup.
A former France Under-20 international joined Guingamp from Sochaux in 2017.
