Arsenal's superior quality ultimately showed in their 4-1 north London derby win, but they were also very clever with the way they exposed Tottenham's tactical weaknesses too.
Spurs' 3-5-2 shape under new boss Igor Tudor, and the fact they did not just sit in, left space for Arsenal to exploit in forward areas on Sunday.
The Gunners ran away with the game in the end but, in the first half, when it was still in the balance, the area where they had the most attacking edge was down their right-hand side, where Bukayo Saka and Jurrien Timber were dominant.
It's never easy to stop a team like Arsenal when so many of their players are playing well, but what the Gunners did really well was produce moments of quality or skill in attack when it mattered.
They looked back to the levels we have seen them perform at for so long this season - this was a great performance by them, not just a brilliant result.
