The 21-year old right-back hammered home a 25-yard strike in the 73rd minute that caught Gunners keeper Wojciech Szczesny by surprise to give Spurs an unforgettable derby win and he was delighted with his contribution after the match.
"It doesn't get much better than that. I just picked the ball up and hit it,” he told Sky Sports1.
"I just thought why not have a go. If you don't buy a lottery ticket you don't win the lottery.
"Arsenal are a good team and we found it difficult at times but we dug deep and got the result that we wanted."
