The diminutive Frenchman stole the show for the Blues last term as Chelsea cruised to the title.
He's started well again this term and scored against his old team Leicester at the weekend.
Kante was crowened as the PFA Player of the Year last term and could be on to do the double if he carries it on.
And Conte is delighted with the way he is improving.
He said: “N’Golo is very important for us – a top player.
"It was an amazing performance. He played a really fantastic game.
“He scored but, overall, he made a lot of good runs. He is always improving.
"I think now he is very good with the ball.
“Before, a lot of people told me, ‘Yes, without the ball, he has good stamina and is a good worker’, but now with the ball he has improved a lot.
“I am happy for this because we are working a lot with him.
"To be the best player in the Premier League last season is a great thing.
"This season he is confirming it.
“You must have the will to work and improve.
"Until the end of your career you can always improve.”
Kante is a likely starter when Chelsea start their Champions League campaign against Qarabag tomorrow.
