Harry Kane's textbook header on 49 minutes ultimately won the game and the goal sparked a thrilling spell where we threatened to run riot.
Harry glanced a header just wide from six yards, Dele missed a one-on-one and Petr Cech produced a string of saves to deny Harry, Kieran Trippier, Erik Lamela and Christian Eriksen.
Of course, these derby games are never quite clear-cut and at 1-0, Arsenal had a chance to snatch a late leveller in injury time only for Alexandre Lacazette to slide a one-on-one chance wide.
That was the only time Arsenal got in behind us as the efforts on goal stats rose to 18-6 in our favour - three of the Gunners' efforts arriving late in the game.
