Panic over. After a frustrating start to the season Arsenal have finally flourished, outclassing Watford in a first half they illuminated with excellent approach play and clinical finishing. The only significant criticism would be the failure to sustain their superiority for the full 90 minutes, allowing a home side that had been humbled before half-time to find a measure of encouragement in the latter stagesbut though the Hornets wrestled their way back into the contest they never looked likely to avoid losing it.
