Tottenham captain Heung-min Son admitted frustration after defeat at home to Arsenal.

Son and his Spurs teammates came from 0-3 down at halftime to eventually lose 2-3 on Sunday.

The captain later said: "We could have come back.

"I feel that we had a good chance and good opportunities.

"They were clinical and strong in the air. We had plenty of chances, we hit the post and had a goal disallowed."

Tottenham conceded two goals from set pieces, and it was especially those that troubled the South Korean star after the game.

"As I said before, this is a big game and we had to be strong on set pieces.

"Arsenal are of course good, but I think everyone needs to pick themselves up. Now we are working on the set pieces, staying strong and clawing at it."
