Tottenham boss Mauricio Pochettino admits he loved beating Arsenal.
With five minutes remaining, Nabil Bentaleb angled a cross from the left and Harry Kane planted a classic centre-forward's header back across David Ospina and home.
"I jumped, I shouted, it was a special moment, a brilliant moment," said Pochettino.
"It was a fantastic performance. I'm very pleased for the players and congratulate them for a fantastic game. I'm very happy for our supporters. It was a great atmosphere at White Hart Lane."
