The England international thought he had done enough to win the north London derby for his side before seeing 10-man Gunners escape with a point
Tottenham striker Harry Kane conceded to being disappointed with the 2-2 draw against Arsenal after his spectacular goal prompted "a flood of emotions".
Arsenal struck first as the north London rivals sought to gain ground on Premier League leaders Leicester City at White Hart Lane, with Aaron Ramsey cleverly backheeling past Hugo Lloris in the 39th minute.
But the visitors' hopes of victory appeared to unravel entirely after Francis Coquelin hacked Kane down to be sent off in the 55th minute.
Toby Alderweireld levelled with an hour played, two minutes before Kane steered home a magnificent angled strike – tearing off his protective face mask in celebration.
"We're very disappointed," Kane told Spurs' official website.
"We needed to kill it and get a third. That's football. We'll deal with it and move on."
Kane netted his 20th goal of the season by putting Spurs 2-1 ahead and admits the occasion was special to him.
He said: "I got it out of my feet and thought 'why not?', so to see it go in meant a flood of emotions."
