Son Heung-min scored Tottenham's lone goal in their 1-0 win over Crystal Palace.
Mauricio Pochettino believes Son can be a hero for Spurs.
"[Can Son be] Another hero? Yes, why not!" Pochettino said in his post-match press conference. "Against Qarabag he scored twice and now he scored the winning goal. The energy he showed was amazing and because of that I think our supporters are very happy with him. Son is a player that we followed for a long time. He can play in lots of different positions in attack. At all clubs, when you sign a player the expectation is big, and I'm happy because he's scored twice on Thursday and again today.
"We wanted to sign him because it's a profile that we like. He shows a lot of energy and presses high with a high tempo, and this is one of the skills he has."
