The South Korean star joined Spurs in a big-money move on Friday.
When asked to identify the traits that convinced the Spurs boss to move on the former Bayer Leverkusen winger, Pochettino said: “He’s a player that can give us pace, he has good qualities from both feet and he has experience in the Champions League and Germany.”
“He is a young player at 23 but with a lot of experience and he will be able to help us achieve our targets,” added the Argentine.
Son’s capture last Friday for around £18 million – according to Sky Sports – made him Spurs’ third most expensive player ever, behind the esteemed Roberto Soldado and Erik Lamela.
Pochettino, and fans alike, will be hoping the South Korean fares better than his pricier counterparts and on the evidence of his career to date, there’s every chance.
Son has performed consistently over the past five years in Germany and has notched an impressive 41 goals in 135 games along the way.
His experience in the Bundesliga will be better preparation for the Premier League than Serie A or La Liga, and his pacey, dynamic nature is a pre-requisite for successful attackers in England’s top flight.
The flying winger looks set to be the antidote to Tottenham’s sluggish start - alongside fellow speed merchant Clinton N’Jie - and it remains to be seen whether further attacking additions will arrive, as the transfer window reaches its final hours.
