In recent years, north London has been white with Spurs finishing above their rivals for the last three Premier League seasons.
But the Gunners went into the clash as favourites after a brilliant summer transfer window.
Meanwhile, Spurs were coming into the game having just lost at home to Newcastle and unsubstantiated rumours that this could well be Mauricio Pochettino’s final game in charge.
But it was the away side that took an early lead.

A counter-attack saw Erik Lamela break free. Bernd Leno could only palm Lamela’s fairly tame effort into the onrushing Christian Eriksen who couldn’t miss.
And Spurs were given the perfect opportunity to double their lead when Granit Xhaka made a quite ridiculous tackle on Son Heung-min in the penalty area.
Harry Kane stepped up and made no mistake.
But just when Spurs looked to be taking a 2-0 lead into the break, Arsenal got back into the match after a brilliant finish from Alexandre Lacazette.
And that goal set the tone for the second-half in which Arsenal dominated.
But it took until the 71st-minute for Unai Emery's side to draw level.
Matteo Guendouzi's briliant cross was stabbed home by Pierre-Emerick Aubameyang to get the home side back on level terms.
Arsenal had all the momentum and went in search of a winner but Pochettino's side will be happy to have held out for a draw.News Now - Sport News
