Wenger probably has evolved, dragged along kicking and screaming partly in response to the long standing realisation (for everyone bar himself) his Barca-lite dream was never going to deliver and partly by blind luck. But his evolution is still offset by stunning mistakes. He's the reason we are struggling in the CL again, for instance. He's also the reason we haven't fully taken advantage of the possibilities this season and are still relying on a second tier player in the most important position on the pitch. Will Giroud's misses cost us? Depends if other players can pick up the slack and compensate. But why should we be in that position anyway? We had the need, we had the money, we just didn't have the will.
