Gnabry penned a new deal with Arsenal last month after making his first team breakthrough.
He told Kicker: "I know the manager is supportive of young players and I know I will get chances at this club.
"Mr. Wenger is a calm type of manager. He talks to me and then he tries to motivate me to do better.
"I also know I have it in my own hands and eventually need to take my chance."
