Spurs kick off their European campaign against Group E rivals Monaco at Wembley tonight in front of a record home crowd for the club.
And Pochettino believes the competition is the perfect showcase for the talents of last season’s Premier League top scorer, who won the Golden Boot with 25 goals.
The Tottenham boss said: “He’s one of the best in the world, not just in Europe. To show it in the Champions League is a good challenge for him.
“It’s a big challenge for him. He’s very young, last season top scorer in Premier League. We can expect more, but only patience when he doesn’t score. He’s a top player, top quality.”
Kane only has one goal to his name from four games this season, finally opening his account in Saturday’s 4-0 win at Stoke.
His slow start followed a disappointing Euro 2016 campaign with England and a change of role to a deeper position in some games for Spurs this season.
