Harry Kane inspired Tottenham to a 1-0 victory over Arsenal in front of a record-breaking crowd at Wembley.
The second-half goal from Kane was the striker’s seventh in seven games against Arsenal in the English top flight.
Alexandre Lacazette had a golden chance to equalise at the death but the Frenchman fired the ball under the body of Petr Cech and past the post from close-range.
A crowd of 83,222 packed into Wembley to see Spurs beat their north London rivals, an all-time record attendance in the Premier League.
The two sides played out a first-half lacking any real quality, with only one shot on target recorded in the opening 45 minutes at Wembley.
Pierre-Emerick Aubameyang and Henrikh Mkhitaryan struggled to replicate the form they both showed in the 5-1 thumping of Everton.
Mkhitaryan was particularly wasteful in key positions for the Gunners, while Jack Wilshere and Mesut Ozil were largely anonymous.
Spurs flew out of the blocks in the second-half, with Arsenal camped deep inside their own half, and Kane finally made the away side pay in the 49th minute.
Ben Davies whipped an enticing cross from left to right and Kane was able to nod the ball back past Cech at the far post.
Kane’s goal had Wembley rocking and Spurs fed off the positive energy sent down from the stands, piling yet more pressure on Arsene Wenger’s men.
England’s talisman grew in confidence as the match wore on, giving a masterclass in centre-forward play and almost set Erik Lamela up Spurs’ second with 20 minutes remaining.
Aubameyang, at the other end of the pitch, meanwhile, cut a frustrated figure as Spurs held on for three points.
The Gabon forward was reduced to a few meaningless touches in the second-half.
If nothing else, Aubameyang and Mkhitaryan should now have learned exactly what north London derbies are all about.
And Kane was the man to teach them a lesson at Wembley.
