A loss, though, would mean Spurs close the gap to just one-point with two games remaining.
There was so much riding on the game for the Gunners and they started well. They were the better team during the opening 15 minutes.
But things fell apart – and rapidly – for Mikel Arteta’s side.
Things then went from bad to worse after Rob Holding was sent off.
Holding was given a yellow card in the 26th minute after dragging Son down.
He then floored Son with a reckless shoulder charge to the head seven minutes later and was given his second yellow card.
It was a challenge he did not need to make, especially when he was on a yellow card.

Gary Neville, commentating on the game for Sky Sports, couldn’t believe what he had just seen.
“What is he doing? What is he doing? WHAT IS HE DOING?! Oh my goodness….” He said in shock.
Neville added, per the Metro: “I’m watching the run and he has a jab with his elbow, it comes away from his body. He’s been erratic, rash, he’s lacked composure.
“It’s madness. Mikel Arteta has big problems now. His centre-back has caused him huge issues in the first 35 minutes of this match.
“We spoke about Holding earlier in the game. Son played him. He played him and played him, like a little boy.
“Sometimes as a defender you’re head goes, you’re emotional and you do rash things. Son was in his head.”
Arsenal’s task of turning the game around got even harder shortly after when Kane netted his second of the game as he headed home from close range.
It seems the race for the fourth and final Champions League berth is still very much alive.
