The Spurs talent came on for Senegal against England at the World Cup on Sunday, when the Three Lions secured a 3-0 round of 16 win.
While Sarr did not have a huge impact on the game, he did show flashes of his quality.
"Pape has come into the team, he hasn't quite found himself playing a lot of games, yet," stated Kane to reporters before the match.
"But, from what I see in training, he's a really talented player.
“Quite quiet in terms of personality, he just gets on with training and his job.
“He's a good guy, so if he plays tomorrow then obviously I know a few things from training.
“He's a really talented player with some great ability on the ball.
“It's good to see him doing well at the highest level."
