4. Astute

In August 1999, Wenger signed Thierry Henry from Juventus for an estimated £11m. It would prove an absolute steal. Mike Egerton / EMPICS Sport Mike Egerton / EMPICS Sport / EMPICS Sport

5. Tetchy

Considered a calm and level-headed individual, Wenger does cut a frustrated figure occasionally. Here, during a Champions League clash with Valencia in 2001, he wrestles with a ball-boy at the Mestella Stadium as time runs out on Arsenal's journey in the tournament.

8. Builder

2004 proved an incredible year for Wenger and Arsenal. Firstly, they were crowned league champions again after going through the entire season undefeated. Secondly, in October, Arsenal signed the biggest club sponsorship agreement in English football history with Emirates Airlines worth 100 million pounds. The deal would see the company own the naming rights to the club's new stadium.

9. Isolated

In August 2009, Arsenal lost to Manchester United at Old Trafford and Wenger was sent to the stands by referee Mike Dean for kicking a water bottle on the touchline. It's fair to say the home fans enjoyed the experience. Adam Davy / EMPICS Sport Adam Davy / EMPICS Sport / EMPICS Sport

10. Frustrated

By early 2012, the club had failed to win a trophy for seven years. Wenger's position came under threat and he was a man under fire. Here he despairs as Arsenal lose to Chelsea at home.

11. Patient

He finally got his hands on some silverware in May as Arsenal beat Hull to win the FA Cup - the 5th time Wenger won the tournament. Nick Potts / PA Wire/Press Association Images Nick Potts / PA Wire/Press Association Images / PA Wire/Press Association Images
