With the transfer window open, here's a look at five Arsenal transfers which disappointed.
The transfer window is now open again and there is plenty of reason for fans to be excited.
Arsenal fans know just as well as any others that signings do not always pan out and are not instant fixes they desire.
Here is a look at five of the more disappointing deals under Arsene Wenger.
Kim Kallstrom didn't let the club down in his limited showings for Arsenal, but to pretend his signing was a success would be bending the truth. Arsenal fans were expected a star striker to be signed permanently a year ago to aid their title push, instead they got a 31-year-old midfielder on loan. His signing became farcical when it transpired he had a fractured back, meaning he was unable to cover the absence of Aaron Ramsey in midfield who was out with injury. He is now back at Spartak Moscow.
Jermaine Pennant became England's most expensive teenager when he signed for Arsenal, but he rarely looked like fulfilling his potential. A hat-trick against Southampton was his one and only highlight, displaying a fleeting glimpse of what could have been. A wayward attitude and impatience saw him leave the club and even land up in jail at one point, and at 31 he was an unsigned free agent over the summer before agreeing a short-term deal to play in the Indian Soccer League.
Arshavin was seen as the missing piece of the jigsaw at Arsenal, a proven top class player who could elevate them towards silverware. It started promisingly enough, with the Russian incredibly scoring four goals away to Liverpool, but his lack of application for the defensive side of the game saw him fall out of favour with manager Arsene Wenger. Whether he was ever really utilised properly from a tactical perspective will remain the subject of debate among fans, but he did not help himself with his questionable attitude and inconsistent performances when he was given chances.
Richard Wright was hailed as the successor to David Seaman and there were high hopes for him when Arsenal paid £6 million to sign him from Ipswich Town. He failed to make an impression, with Stuart Taylor even dislodging him in the pecking order and impatiently pushed for a move to Everton where his career continued to stagnate. Somewhat surprisingly he is currently contracted to Manchester City, where he is in this third season as a back-up, and is yet to play a competitive game.
Infamously hailed by Arsene Wenger as Arsenal's 'fox in the box', Francis Jeffers was more like a cat in a sack. Prolific at under-21 level for England, Jeffers never translated that form and his promising early performances for Everton into anything of substance for Arsenal after the club paid £10 million to sign him. Now 33, Jeffers' career is all-but-over, without a club since playing for Accrington Stanley a year ago.
