Last season Kante became the first outfield player to win successive Premier League titles with different clubs.
Conte always believed there was room for improvement in the midfielder's game and he now believes the hard work has paid off.
The Blues boss is keen for the French international to mentor for summer recruit and compatriot Bakayoko, who is expected to fill Nemanja Matic's role.
"Last season I said during many press conferences about N'Golo that he could improve a lot with the ball," said Conte ahead of the heavyweight clash with Arsenal on Sunday. "He's working very hard to improve this weakness.
"But I think now he's a complete player - he's a top player with the ball, without the ball. He always knows when he has the ball what he has to do.
"Baka without the ball is a really strong player, a physical player. He can improve a lot with the ball. We are working a lot on this aspect with him.
"We try to play with an identity and if you want to give an identity to your team, every single player needs to know very well your idea of football. To have in your team a powerful player is very important, above all in this league."
Meanwhile, Bakayoko himself is being helped by the influence of Didier Drogba, a man who caused Arsenal so much pain in his time with Chelsea.
'Chelsea has always been a club I liked since I was young, especially because of guys like Didier Drogba being here,' said Bakayoko, who scored his first goal for Chelsea against Qarabag on Tuesday.
'I would make a point of watching their games and I had this club close to my heart growing up, so I'm really happy to be wearing their shirt. I made the choice to come to Chelsea a lot because of the coach and after speaking to him. And I spoke to the people around me and my family. It seemed like the best opportunity.'
