Conte paid short-shrift to the possibility of Real Madrid luring away his first-choice goalkeeper, insisting that there was little to clarify over Courtois' future.
"I think it is not important to clarify the situation," Conte said.
"Thibaut is, for me, one of the best if not the best goalkeeper in the world.
"He's worked very well, he is a fantastic goalkeeper. He stays with us and this is the most important thing.
"The other situations for me are only speculation."
"He's playing very well and you can see that he is not only very good with his hands but also with the feet," Conte added.
"I think he is a complete goalkeeper, he is a modern goalkeeper and for me now he is one of the best in the world.
"I don't want to tell him he is the best because he is my player, but he is a fantastic goalkeeper. He is at the top."
