Ex-Gunner Conor Henderson played for Championship Yeovil and scored in a behind closed doors friendly. The Republic of Ireland under-21 international left the Emirates in the summer and lasted an hour of his first game since the end of the season.
Boss Gary Johnson added: "You can see that he's not quite fit just yet so we're really just having a look at him because we were asked to have a look at him.
"He's been a top player, of course, but he's had a cruciate ligament injury, which is a big injury, and we're just taking a look.
"We gave him an hour today and you could see the Arsenal in him. Of course, he's a long way away from match fitness at the moment."
