Former Southampton player Matt Le Tissier made his competitive debut for Guernsey after 11 years away from the game.
The 44-year-old, who retired from football in 2002, signed for the club who play in the Combined Counties Football League Premier Division earlier this month.
Despite coming on for the last 10 minutes, the ex-England international was unable to turn the club's fortunes around as they suffered a 4-2 defeat at the hands of Colliers Wood.
"In all honesty, while it might be exciting for the fans, it's not a good sign for us," Guernsey assistant boss Colin Fallaize told BBC Guernsey. "It means we were struggling to get a squad together.
"Matt's as good as gold and travelled down to help us out with squad numbers, but as Matt would also say himself, it's not a good sign that he's there as it means we're in trouble numbers-wise."
Guernsey have now played 11 of their 16 scheduled games for the month of April.
