Kante says he had contact from Mourinho while considering his future with Leicester City.
He told L'Equipe magazine: "Why did I choose Chelsea, despite José Mourinho's phone calls? It was a difficult choice.
"It could also have been good to play the Champions League with Leicester. The first contact was with (Antonio) Conte. He had a clear idea of my profile, what he wanted for me, a two-field midfield shot. He explained how he worked, tactically, and why I would learn a lot from him.
"And, above all, he wanted to win!"
