Arsenal's outing at Stamford Bridge went far better than 7 months ago. In a competitive match, Arsenal only conceded twice, to a brilliant run from Eden Hazard that led to a penalty, and then to a late counter attacking goal by Diego Costa. Unlike last March, Arsenal were defensively sound, as Arsenal set up to counter attack. Frustratingly, Arsenal's attack was poor, with a lack of cohesion, strength and quick decision making. All of Arsenal's newest signings, Mesut Özil, Alexis Sánchez and Danny Welbeck failed to impress, while Santi Cazorla and Jack Wilshere were bright but not decisive enough. In that sense, it's not hard to question the selection of Mesut Özil in a wide position, when there are better options. Perhaps it'll make sense in 6 months' time, but Arsenal are in a position where they are already on the cusp of being out of the title race, and are 3 points worse off from last year's corresponding fixtures. Instead of building on the platform of winning a trophy, Arsenal have decided to restructure it.
On the plus side, Arsenal Wenger bodied Jose Mourinho, and then challenged the press corps to a fight. If you can't get enjoyment out of that, you can't get enjoyment out of anything.
