Arsene Wenger celebrates his 18th anniversary as Arsenal manager today.
The then-unknown Frenchman took over at the Gunners on 1 October 1996, replacing Bruce Rioch, and has since won 13 major honours at the club.
The manager has gone down in Gunners' folklore as their greatest manager, who has made some incredible signings - Henry from Juventus, Vieira from AC Milan, Ramsey from Cardiff.
However, it has not been all plain sailing in the transfer market. Who could forget Francis Jeffers, Igors Stepanovs, or Andre Santos.

Show all 11 1 /11Arsene Wenger's worst signings XI Arsene Wenger's worst signings XI Richard Wright After impressing at Ipswich, Wright was signed in 2001 as the heir to David Seaman's No 1 shirt, but his time at Highbury was remembered for error after error, and he was eventually usurped by young Stuart Taylor
Arsene Wenger's worst signings XI Oleg Luzhny Known as "The Horse" for his galloping runs, but played like he was wearing blinkers. Joined from Dynamo Kyiv in 1999
Arsene Wenger's worst signings XI Igors Stepanovs Tried to marshal the Gunners against Manchester United at Old Trafford in disastrous consequences, the team conceding five before half-time and memorably losing 6-1. Latvian signed from Skonto Riga in 2000
Arsene Wenger's worst signings XI Sebastien Squillaci French international joined for £4m from Sevilla in 2010. Made 39 largely woeful appearances for the club, and left on a free last year
Arsene Wenger's worst signings XI Andre Santos The least said about Santos the better. Wenger said the "quality" left-back had "Champions League experience" when he was signed from Fenerbahce for £6.2m in 2011 but he had yet to play even in the full competition. Was he even talking about the same player?
Arsene Wenger's worst signings XI Junichi Inamoto The Japanese midfielder joined from Gamba Osaka in 2001, in a move that was portrayed as a cynical marketing ploy for the Gunners to tap into the Far East market. The doubters had a point, he failed to make a Premier League appearance for the club before leaving to join Fulham a year later
Arsene Wenger's worst signings XI Amaury Bischoff Wenger admitted he had taken "a gamble" on signing the injury-hit Portuguese midfielder in 2008. The gamble didn't pay off - he only played one Premier League match for the Gunners before leaving the following season
Arsene Wenger's worst signings XI Gervinho He may now be setting the world alight for Roma in Italy, but the Gervinho at Arsenal was a different beast - one that could not cross or shoot, and confused himself when he was running with the ball
Arsene Wenger's worst signings XI Park Ju-Young Park who? I hear you cry. Despite scoring on his debut, the South Korean striker only ever made seven appearances in three years at the club. He is now paying his trade on loan at Watford
Arsene Wenger's worst signings XI Marouane Chamakh The Moroccan target man joined from Bordeaux with fine Champions League pedigree. Unfortunately he did not ever get close to replicating this for the Gunners
Arsene Wenger's worst signings XI Francis Jeffers The "Fox in the Box" was not a wily signing for £8m. He scored eight goals during his time at Arsenal, meaning every goal he scored set the club back a cool £1m
The Gunners take on Galatasaray in the Champions League tonight, hoping to celebrate Wenger's anniversary in winning fashion.
