The Frenchman, who took the reins in 1996, enjoyed a fruitful first decade with the Gunners, winning three Premier League titles, three FA Cups and four FA Community Shields under his stewardship.
From 2005-06 onwards, however, the North Londoners have not been as successful, enduring a nine-year trophy drought which coincided with the switch from Highbury to the Emirates.
Although Arsenal did go on to win three FA Cups between 2014 and 2017, the league title has eluded them since 2004, and in recent years, the Gunners fanbase has become increasingly critical of Wenger's tenure at the club.
Wenger, who will be stepping down as manager at the end of the season, has stated that working with "restricted resources" following the stadium move and still keeping the club in the top four year after year was his best achievement.
"I would say, personally, from 2006 to 2015 - it was certainly the period where I needed to be the strongest and did the best job," Wenger told Sky Sports News.
"To accept to commit to five years when you build the stadium and to work with restricted resources and keep the club in a position where we can pay our debts back.
"I personally feel I did my best job in that period. Not the most glamorous, maybe, but the most difficult."
Wenger's final game in charge of the club will be away at Huddersfield Town on Sunday, May 13.
