Emmanuel-Thomas picked up some valuable first-team experience last season during loan spells at Blackpool and Doncaster.
Wenger believes the 19-year-old has a bright future at Arsenal.
"Jay has class. Class to give the ball, class to finish, class to pass people," Wenger declared.
"I believe he can play against anybody and score goals, but then again you must earn your place and on a daily basis he must show you have the hunger and quality.
"He has the needed quality without a doubt. I am confident that if he gets an opportunity he will show that."
