The Frenchman, 66, was unveiled as Gunners manager on the 22nd of September back in 1996 and has now clocked up a remarkable two decades in charge of the one club.
During his time in charge of the North London club, Wenger has won three Premier League titles (1998, 2002 and 2004), six FA Cups and six Community Shields for a total of 15 trophies.
His most successful season was the 2003/04 campaign in which the 'Invincibles' went undefeated in their 38 league games for an overall unbeaten run of 49 matches.
From a personal viewpoint, Wenger has been named Premier League Manger of the Year on three occasions ('98, '02 & '04) and the League Manager's Association Manager of the Year twice ('02 & '04) and was inducted into the English Football Hall of Fame in 2006.
Through his Premier League days (since 1992) of those 20 years at Highbury and the Emirates Stadium, the former Nagoya Grampus and AS Monaco boss has seen 44 top flight clubs use 232 managers, according to the Daily Mail.
He may have his doubters, but Wenger has endured what not many other people in the modern game have, while consistently keeping Arsenal in the top four domestically and competing each and every year in the Champions League.
Well done Arsene!
