Wenger was delighted with Gnabry's performance against Tottenham and believes the teenager has a bright future ahead of him.
"I integrated him into the first team a long time ago because I see that the qualities are there," he told Arsenal Player.
"He looked to have problems with injuries last season but he was already very influential in the NextGen Series and this season he has grown. He's only 18 years of age and what he shows is encouraging."
