1. We're not moving forward at all, are we?
In the words of Barry Glendenning, we really should have a groundhog as our mascot instead of Gunnersaurus. We love following our team, and in reality it wasn't the worst game of football ever, but in all honesty, there are no signs of recovery, or attempts to improve the defensive side of our game on the training field. Stoke are the tallest side in world football (apparently) so is a plan to stop crosses coming in and practicing it such a terrible betrayal of the beautiful game?
2. Why didn't they listen to him?
Arsene talked about the players not doing what he said. We should therefore ask firstly did he explain it well enough. But above all, all four leagues in England and beyond are full of people who know how they think the game should be played, and have sophisticated plans for how their teams should play. However they lose they jobs because in reality they can't get their teams to do it.
3. Strength and power is a prerequisite for success
I just watched the Newcastle - Chelsea highlights. There were some legal but very tough, strong tackles going in. Plenty. Colback on Fabregas for the second goal is a good example. I think in the modern Premier League you have to match that.
