The under 21s completed their pre-season campaign with a 3-1 victory at Hillingdon Borough, despite going behind to a 4th minute goal.
Ronan O'Rourke equalised in the 26th minute, before the same player put the Greens ahead shortly after the hour mark. Stephen Cunningham missed a penalty in the 80th minute but made amends three minutes later when he completed the scoring.
The league campaign starts next week with an away game at FC Romania.
