The two teams went into the game in very different form with Spurs having suffered back-to-back league defeats to Burnley and Chelsea and the Gunners looking for their fourth win on the bounce.
The Gunners will move to within a point of their neighbours in third if they win at the national stadium and the departing Aaron Ramsey gave them the perfect start with less than 20 minutes on the clock.
However, Harry Kane levelled from the penalty spot in the second half having been fouled by Shkodran Mustafi.
