The 21-year old striker scored his 30th goal of the season for Spurs in their 3-1 Premier League win at Newcastle United on Sunday in his first full season as a regular in the seniors.
Kane became the first Spurs player since Gary Lineker to reach the 30-goal milestone and manager Pochettino feels there can be many more season like this for the recently-capped England international.
"He has big potential. He is young and this is his first full season in the first team. We need to push him to try to improve his level because he has the potential to improve," said the Argentine.
"It's a fantastic achievement and I congratulate him. He deserves this moment because he has worked a lot. It's an historic thing.
"He's happy in the changing room and all his teammates are happy, and I think all our supporters and the club are happy at his achievement."
