#1 At this age, he showed he can still change
When Wenger arrived at London in 1996, the three-man defence system was the more popular choice. He came and revolutionised the system, creating a back four to be supported by four in the midfield and two attackers.
Eventually, the 4-4-2 system was hugely successful as it saw the mercurial combination of Dennis Bergkamp and Thierry Henry wreak havoc in the opposition defence.
With time, the Frenchman adopted to the changing needs and shifted to a 4-2-3-1 formation as he tried to make ends meet with a depleted squad. The results were there to see as Arsenal finished in the top four consistently, albeit without the Premier League title for the last 12 years.
Now, when increasing number of teams are countering the balanced 4-2-3-1 with a more aggressive 3-4-3, Wenger switched to a 3-4-2-1 and defeated the Premier League champions in the FA Cup final.
Therefore, as has been argued by the anti-Wenger brigade that the need for a change has not been felt more than before, Wenger showed if the call of the hour demands, he can still tweak and tinker to produce match winning performances.
