Thebigbangtheo - what you have succeded in posting is confirmation that the current squad is considerably better than Wenger's last squad.
So at the same time it is all the more annoying/disappointing/tragic that we have so far been unable to match Wenger's performances let alone surpass them. When you say we have moved forward as a team, I don't see how, isolated good performances are interspersed with abjectly poor performances. For you to claim an improvement it suggests you are looking/focusing your attention on a limited subset of the performances themselves and not all of it. The table tells a story, after 26 games (2 thirds of the season) we are in 10th place, with the 11th best attack and the joint 3rd best defence in the league.
We have averaged 5 shots per game this season, even during the train wreck of a season last season, we averaged 10 shots per game. In Wenger's final season we finished 6th, had the joint 3rd best attack and the 8th best defence. Again, I struggle to see where we have progressed, holistically.
