The England forward, in a rich vein of form in domestic and European competition, has scored nine goals in five games, including a hat-trick at APOEL Nicosia in the Champions League on Tuesday.
Glenn Hoddle, recently voted Tottenham's greatest player, said Kane could become the club's best-ever striker, an opinion shared by Pochettino.
"Harry is still so young," said the Spurs boss. "For me he is one of the best strikers in the world. He is so young and can improve. He is a professional. [It is] difficult to find many words to describe Harry but he is one of the best in the world. But we cannot put such pressure on Harry as he is so young."
Pochettino, whose side travel to newly-promoted Huddersfield Town on Saturday, has no plans to protect the 24-year-old for the bigger games and has confirmed he will not be given a break just yet.
"Maybe in the future we will decide to rotate. But at the moment he is in a very good condition," he added. "We will hope to avoid any injury with any player. Harry is showing a great condition and there is no reason to rotate or rest him."
Tottenham, fourth in the table after six games, five points off the pace, will be without Mousa Dembele at the weekend due to a new ankle injury, which is separate from a previous foot problem.
