Wenger believes the 18-year-old could become ‘an extremely influential player’ at the Emirates Stadium.
“It’s such great news that Jack has committed his long-term future to the club,” Wenger told Arsenal’s official website.
“Jack is a fantastic footballer with a huge amount of potential, and we have all seen with his performances so far that he is a very gifted player who could be an extremely influential player at the top level of the game.
“At still only 18 years of age, there is still so much more to come from him and we’re all excited by the fact that Jack Wilshere will be an Arsenal player for years to come.”
