PATRICK VIEIRA

Despite being a virtual unknown at the time, Wenger made the combative French midfielder his first target when joining Arsenal and snapped him up for what proved a bargain price of just �3.5 million in 1996. Vieira became the Gunners' inspirational captain during eight years at the club, winning seven club trophies plus the World Cup and European Championships with France.

THIERRY HENRY

Wenger had the foresight to see that the gifted but erratic Henry, who was being played as a winger by Juventus, could develop into an out-and-out striker. The Frenchman soon repaid his �11 million fee, becoming the outstanding striker in Europe and Arsenal's record goalscorer, claiming a glittering array of silverware in the process.

CESC FABREGAS

In terms of a money-making signing, there are few to equal Fabregas. He cost Arsenal just �500,000 in compensation to Barcelona in 2003, and the Catalan club bought him back in 2011 for �35 million after eight years in which he was adored by Gunners fans as the fulcrum of Wenger's eye-catching, if under-achieving, side.

ROBERT PIRES

The French winger arrived from Marseille for a �6 million fee in 2000 and elevated his dashing style to new heights during six memorable years at Arsenal. Was also an amazing value replacement for Marc Overmars who was sold that same summer by Wenger for �25 million. Rated sixth on the all-time list of Arsenal's greatest ever players.

SOL CAMPBELL

Enraged Tottenham supporters when he quit White Hart Lane to make the short trip across north London, joining Arsenal on a free transfer and proving an inspired swoop by Wenger. The England centre-back went on to be the defensive rock of a team that won three FA Cups and two Premier League titles, including going the entire 2003-04 league season undefeated.

And here's two that didn't quite pan out the way Wenger would have wanted:

FRANCIS JEFFERS

Hailed by Wenger as his "fox in the box" after joining from Everton for �10 million in 2001. Sadly his time in north London showed even an astute judge of talent like Wenger could get it horribly wrong as the diminutive striker scored only eight goals in 39 appearances before returning to Everton on loan in August 2003 and then joining Charlton permanently the following year.

ANDREI ARSHAVIN

Arshavin arrived for a then Arsenal record fee of �15 million in 2009 after earning plaudits across the world for his dazzling performances on the wing for Zenit St Petersburg and Russia. But he faded quickly, earning criticism for his lackadaisical attitude on and off the field before being sent packing back to Zenit last year.
