Wenger has high hopes for the speedy teenager.
"We signed Serge Gnabry because I believe that he will be a great player," Wenger said on arsenal.com.
"He's nearly there now, and competes for a regular place in the team in the Premier League.
"He has technical ability, he has power, he has pace, he has finishing quality and he can give a final ball. He's a powerful offensive player and I believe that he will be a great player for Arsenal football club."
