The left sided Martin is playing for the side's U23s this afternoon at Millwall.
The 18-year-old joined Fulham from Maidstone United, making his debut in the U18 set-up in 2015/16 and it seems that the Whites have taken the youngster on trial.
Martin can also play in defence or midfield, having played 12 times for Fulham's U18s this season.
