Spurs won their second game in a row on Sunday, beating Palace 1-0 at White Hart Lane thanks to a goal from new signing Son, who arrived from Bayer Leverkusen last month.
The South Korean international, 23, hit the only goal of the game when he drove at the Palace defence before slamming the ball beyond Alex McCarthy in the Palace goal.
It was an impressive home Premier League debut for Son, who also scored twice against Qarabag in the Europa League on Thursday night - suggesting that he could well become the attacking support Harry Kane has needed so far this season.
Now, pundit Garth Crooks - a former Tottenham forward himself - has spoken to BBC Sport about Son's display, and it's fair to say he was impressed.
Crooks predicted that Son will quickly become a fan favourite at White Hart Lane thanks to his energetic performances, and his desire to get on the ball at all times.
"I love this boy's energy," said Crooks. "Son Heung-min scored two goals in midweek in the Europa League and against Crystal Palace showed an alarming willingness to always make himself available to receive the ball anywhere on the pitch. Based on what I've seen so far I think this lad is going to be a big hit with Spurs fans," he added.
Capable of playing out wide, behind the striker or even up front, Son is a versatile attacking option for Mauricio Pochettino, and with three goals in his first three games for the club, he has made an ideal start to life in North London - now he just has to carry that on throughout his time with Spurs.
