The 17-year old German-born winger appeared for the first time for the Gunners in the Capital One Cup against Coventry City last month and has since made substitute appearances against Norwich City in the Premier League and Schalke in the Champions League.
Ahead of some more likely exposure in Tuesday's league cup clash with Reading, Gnabry says he is hoping he can again get some first-team experience as he continues to develop in North London.
"I was just happy to get the chance to get on against Norwich and try to help the team," Gnabry said.
"Like all players, I prefer to start games, but when you watch from the bench you become anxious to get on and play and do something. It was the same against Schalke and that is why I felt comfortable.
"I enjoy football and so a chance to play for Arsenal was one I was eager to take to help the team, but also to show what I can contribute.
"I have a lot to learn and improve on and one way is to play games. It is a big challenge, but one I am enjoying and the fact that the whole team helps me makes it easier."
