I didn't see the match (sometimes teaching gets in the way of even the highest priorities). Apparently, Jack Wilshire, who was just about the only Gunner who played a good match this past weekend again Man City, put on another man-of-the-match display, and scored the game winner in the final minutes. I hope to watch a replay this evening. According to reports I read, the entire Arsenal squad played better; but (a) they could hardly have played much worse (at least compared to the first half of the Man City match), and (b) it's easier to play well against lower-level opponents.
Next up for Arsenal in the FA Cup is a trip to Brighton.
