Thursday 12th October 2017 marks 21 years to the day that Arsene Wenger took charge of Arsenal for the very first time, and it is truly incredible that the man remains at the helm.
The 67-year-old has overseen tremendous success during his time at firstly Highbury and secondly the Emirates Stadium, and there is no doubt he is one of the greatest managers the Premier League has ever seen.
Things haven't been quite so rosy over the past 10 years, and the last few seasons in particular have made some Arsenal supporters lose sight of some of Le Professeur's achievements.
But for all his critics of recent years, he is certain to go down as one of the most recognised managers of all time. Here are some of his most memorable moments as Gunners boss.
9. Arsene Wenger: Arsenal Manager
Former boss of Japanese club Nagoya Grampus Arsene Wenger was appointed manager of Arsenal Football Club in August 1996, replacing Bruce Rioch at the helm.
That was greeted by widespread scepticism by fans who were expecting the announcement of one Johan Cruyff - he had been touted as a future technical director of the FA, but was little known in English football at the time of his arrival in London.
His first game in charge was a 2-0 away win over Blackburn on October 12th 1996, and fans were not to know at this point that the Frenchman would remain in charge for at least 21 more years, bringing them incredible success along the way.
8. First Premier League Title/First Foreign Double-Winning Manager
Wenger has won the Premier League three times throughout his 21-year tenure, the first of which came back in 1998.
The club actually sat sixth in the table at Christmas and looked seemingly out of contention for the title - it was Manchester United's to lose, and bookmaker Fred Done had even paid out on the Red Devils to seal a fifth title in six years.
But the Gunners, under the guidance of Wenger, managed to claw their way back up the table thanks to a win at Old Trafford courtesy of a Marc Overmars goal, and a nine-game winning streak which sealed Wenger's first Premier League title.
He also won the FA Cup that season, meaning he became the first ever foreign manager to win the double in England.
7. Signing Unbelievable Players (...and Some Terrible Ones Too)
Being in charge of one club for 21 years has meant Arsene Wenger has had to constantly change players in order to stay competitive.
For the most part, Wenger has introduced English football to some of the best talents football fans have ever seen; from Thierry Henry to Dennis Bergkamp and Robert Pires to Patrick Vieria, he has unearthed some truly incredible players during his time as manager.
Even recently Wenger has signed some top class stars, including Cesc Fabregas, Robin van Persie, Santi Cazorla, Mesut Ozil, Alexis Sanchez.
No manager can avoid making the occasional dud signing though, and Wenger has been no exception - Sebastien Squillaci, Pascal Cygan, Igor Stepanovs, Nicklas Bendtner, Andre Santos and Francis Jeffers didn't exactly set the world alight...
6. Water Bottle Hissy Fit
Although generally quite a cool customer on the touchline, Wenger has been known to release a fiery side every once in a while.
A truly memorable moment came when the Frenchman took out his frustrations of conceding a late goal at home to bitter rivals Tottenham, no less.
Defender Younes Kaboul headed a Rafael van der Vaart free-kick past Lukasz Fabianski to win the game 3-2 late on and seal all three points for Spurs - and it was their first victory at Arsenal in 17 years.
The result also stopped the Gunners from going top of the Premier League, but with plenty of games left to play in the season, it was no doubt the nature of the defeat and losing their fantastic record that was so irksome - so annoyed was Wenger, that he took out his frustrations on an innocent water bottle after drinking from it in a truly hilarious clip.
5. Coat Fails
Arsene Wenger and that bloody coat.
The poor man has been struggling for years with it, so much so that it has become one of the things people first think about when they think of him.
That fiddly zip and those darn pockets seem to give him far more trouble than any of it's really worth, and it's just definitely one more memorable thing about a huge figure in the game.
4. Sent Off at Old Trafford
Arguably one of the most iconic images in Premier League history...
Managers get sent off, they get rowdy, it happens. Normal procedure is to leave the technical area and go and sit high up in the stands somewhere in a designated area.
For some strange reason in 2009, Old Trafford seemed not to have this designated area, forcing a dismissed Arsene Wenger to climb atop some random plinth to stand in a sea of Manchester United fans.
It's safe to say those fans had an absolute field day, and it remains one of the most memorably funny things in football to date.
3. FA Cup Master
Wenger hasn't won the Premier League title since 2004, but he hasn't been shy about claiming the FA Cup of late.
Some people are quick to play down the FA Cup these days but it remains the most prestigious cup competition in English football, and Wenger has won the thing three times in the past four seasons and that deserves a lot of credit.
His success is a reminder that Wenger still has it in him to win silverware, and he has now won it seven times which is bettered by no one.
When you're around for so long you're bound to make a few enemies along the way, and Arsene Wenger has had his fair share of scuffles.
He had a particularly feisty relationship with former Manchester United boss Sir Alex Ferguson before things cooled down towards the end of the Scot's tenure.
He has also had a few bust-ups with Jose Mourinho, and the pair remain fairly frosty with one another to this day, especially after the Portuguese's 'specialist in failure' comments from a few years ago.
Wenger can get nasty when he needs to, as Alan Pardew once found out when he was manager of West Ham - he didn't respond well to Marlon Harewood's winner in 2006 and gave Pards a royal shove, for which he was fined £10,000.
1. Forging the Invincibles
The most memorable thing about Arsene Wenger's 21-year Arsenal tenure to date is probably the fact that he managed to create arguably the best team in Premier League history - the Invincibles.
He assembled a truly world class team, with the perfect mixture of players to deliver success - the incredible goalscoring efforts of Thierry Henry, the creative spark of Dennis Bergkamp, the steel in midfield of Gilberto Silva and in particular, captain Patrick Vieira.
Two excellent wingers in Freddie Ljungberg and Robert Pires, and an impenetrable defence with the likes of Sol Campbell and Kolo Toure.
Wenger's men stormed to the Premier League title in 2004, having made mathematically sure of glory at White Hart Lane of all places, and that has probably been the height of his achievements as manager of Arsenal football club... so far.
