Tottenham goalkeeper Hugo Lloris saved Pierre-Emerick Aubameyang's penalty to earn a point against Arsenal on Saturday.
Spurs captain Harry Kane had earlier scored from the spot to draw the home side level at Wembley, reports BBC.
Aaron Ramsey - who moves to Serie A champions Juventus in the summer - rounded Lloris to put the visitors ahead 16 minutes into his final derby.
The Gunners finished the game with 10 men following Lucas Torreira's late red card for a tackle on Danny Rose.
