I think we got hurt by individual performances more than any team failure, Monreal wasn't at his best, Giroud fluffed a few chances in quick succession and didn't redeem himself like Negredo, Ozil wasn't able to/didn't put in 100% effort, and Wilshere gave away the ball tons of times. The referee's decision making was terrible of course, but City took their chances well and created more against us than any other team this season. Koscielny getting injured was more of a morale blow (in this specific game), as Vermaelen didn't seem that bad to me, not as good as Koscielny but not bad either. Of course, Koscielny being gone will hurt us, but hopefully he's not out for too long and Vermaelen will be capable enough. It was great to see Walcott back, he played great today and was exactly what we were missing in our poor performances earlier in the season. Now we have a nice 9 day rest before the Chelsea game, we'll hopefully come firing on full cylinders then.
