Although he gained a reputation as a cautious operator in the transfer market, Arsene Wenger has undoubtedly signed some players who have turned out to be major disappointments in an Arsenal shirt:
Despite making a good start in his first few months at the club after joining in 2010, things quickly went downhill for the Moroccan, who ended up looking permanently bereft of confidence, scoring just one league goal in his final two and-a-half years in an Arsenal shirt. He is now with Crystal Palace, having been released by the Gunners in the summer.
Signed from Lille in 2002, Cygan rarely impressed in Arsenal colours, and was often prone to defensive errors. Making 63 Premier League appearances in four years, throughout that time he was seen as a major disappointment, and found himself down the pecking order behind the more reliable duo of Sol Campbell and Kolo Toure.
Hardly anything has been seen of the South Korean striker since he arrived at the Emirates Stadium in 2011, and in over two years in North London he has played just eight minutes of Premier League football, making one question why he was signed in the first place. He spent the whole of the 2012-13 season on loan at Celta Vigo, although he has returned for the current campaign.
Hotly tipped to be a future star of English football, Jeffers was signed by Wenger from Everton for £8m in 2001. It was not money well spent, as the Liverpool-born striker made just 22 league appearances in three years, scoring just four goals. Since then he has led a nomadic career in England, Scotland, Australia and Malta, with League Two side Accrington Stanley his most recent club.
Jose Antonio Reyes
Like Chamakh, Reyes had a decent start to his Arsenal career, scoring on his debut against Chelsea, and in each of the first six games of the 2004-05 season. However, these proved to be rare highlights for the Spaniard, who struggled for consistency on the whole, and never really adapted properly to life in England. He returned to his native Spain in 2006, after another disappointing campaign.
