Arsene Wenger has made some truly exceptional signings during his 20-year spell at Arsenal, but not every player the Frenchman has brought to the club has been a resounding success.
For every Thierry Henry there has been a Marouane Chamakh and for every Patrick Vieira a Kim Kallstrom.
So who makes the grade in a select XI of Wenger's worst signings?
GK - Richard Wright:
Wright was signed from Ipswich in the summer of 2001 for £2.5 million as the expected long-term successor to David Seaman.
He failed to establish himself at Arsenal, however, and after suffering an injury in the Gunners' Champions League match against Deportivo La Coruna, he slipped to third-choice in the pecking order behind Seaman and Stuart Taylor.
He was shipped out to Everton one year after he signed for Arsenal after making just 22 appearances for the club.
RB - Nelson Vivas:
Although the Argentine arrived to London in 1998 with a big reputation, he never justified his £1.6 million price-tag.
With 39 caps for his nation, much more was expected of the full-back, and he made only 69 appearances for the Gunners (40 as substitute) before being released upon the expiry of his contract in 2001.
LB - Andre Santos:
There really was only one candidate for the left-back spot. The Brazilian was part of Wenger's last minute supermarket sweep transfer dash in the summer of 2011 when he was brought into the Emirates from Fenerbahce for £5.9 million.
He struggled to keep up with the physical demands of the Premier League, and riled Gunners fans in 2012 by swapping shirts with Manchester United's Robin van Persie at half-time with his side trailing.
He left in the summer of 2013 after being released by the club.
CB - Igors Stepanovs:
The Latvian was signed by Wenger in 2000 for £1.35 million, following an injury to Tony Adams.
His career at Arsenal was epitomised by his woeful performance in the Gunners' 6-1 defeat to Manchester United at Old Trafford in 2001 where he was tormented by Dwight Yorke for the full 90 minutes.
He was released in the summer of 2004 after making just 31 appearances for Wenger's side.
CB - Sebastien Squillaci:
The Frenchman was brought in from Sevilla for a fee in the region of £4 million, and instantly displayed his total incompetence in the heart of the Gunners defence.
He made a series of high profile mistakes and was quite clearly not ready for the intensity of the Premier League and was released in the summer of 2013.
CM - Kim Kallstrom:
One of the strangest signings of Wenger's tenure. The Swede was brought into the club during the January transfer window of 2014 on loan until the end of the season.
Many Gunners fans were crying out for Wenger to spend as their title challenge was beginning to derail, but instead the Frenchman chose to bring in the Spartak Moscow midfielder, who amazingly had a damaged vertebrae at the time.
He did not make his debut until March 25 and eventually returned to his parent club after making just four appearances for Arsenal.
RM - Amaury Bischoff:
Not many will remember the Portuguese midfielder's time in London, and for good reason.
He made only three appearances for Arsenal after arriving in 2008, before leaving the following summer. Wenger claimed he took a gamble on the player's talent - one which quite clearly did not pay off.
LM - Junichi Inamoto:
The young Japanese supposed future superstar was brought to Arsenal in the summer of 2001 on loan from Gamba Osaka.
He failed to hit the heights that were expected of him however, making just four appearances for the senior team before moving on to Fulham the following summer.
LF - Jose Antonio Reyes:
The Spaniard was one of Wenger's more expensive recruits when he signed from Sevilla in 2004 for a fee which eventually rose to £17 million.
He proved to be utterly lightweight, however, and could not handle the physicality of the English game.
He scored just 23 goals in 110 appearances for Arsenal before being sold to Atletico Madrid for a fee in the region of £10 million in 2007.
RF - Park Chu-young:
Another of Wenger's panic buys in 2011, the South Korean arrived from Monaco for a fee of around £3 million.
The reasoning behind the signing was never made clear, because Park was never really given an opportunity and only made seven appearances for the Gunners before being released in 2014.
CF - Francis Jeffers:
The up and coming English striker was brought in from Everton in the summer of 2001 for a fee believed to be in the region of £10 million.
Jeffers moved out of his comfort zone, but his game was nowhere near the required standard for a striker expected to help his side challenge for Premier League title's and European glory.
He scored just eight goals for the Gunners and was sold to Charlton Athletic in 2004 for a meagre £2.6 million.
Here is how the team would line up:
There were so many players who nearly made the side, including the likes of Pascal Cygan, Philippe Senderos and Marouane Chamakh.
Who do you think should be in the worst signings XI and is there anyone in the line-up who is undeserving of their place?
