Juve and Tottenham are due to meet in the Champions League.
"For me he's an amazing player and still young, so Tottenham are lucky to have him," Khedira told BBC Sport.
"Harry Kane for me is maybe the most complete striker, actually. There is also Robert Lewandowski and Higuain too, but he is strong, good with his head, fast, good with his feet, can score with one touch, he can dribble."
The former Real Madrid man also claimed that Tottenham are “one of the best teams in Europe."
“I watched them a lot this year, against Liverpool and Arsenal. They are strong, because they have good defending, a really good midfield, a world class attacking line and a really good coach," he added.
