“The opportunity to work with Antonio Conte, a brilliant coach, and some of the best players in the world was simply too good to turn down,” said Kante.
Foxes receive club record fee
Leicester said they accepted a club record fee on Friday before Kante finalised terms and completed a medical.
“Despite the offer of a substantially improved, long-term contract, it became apparent that N’Golo’s wish was to join Chelsea,” said a Foxes statement.
Leicester striker Jamie Vardy turned down a move to Arsenal earlier in the summer, but there is continued speculation winger Riyad Mahrez could leave.
Chelsea technical director Michael Emenalo described Kante as a “fantastic” signing with “exceptional quality”.
“He is a perfect fit in terms of Antonio Conte’s philosophies and the style of football he wants to play,” added Emenalo.
Meanwhile, Conte lost his first game in charge as they were beaten 2-0 by Rapid Vienna in a friendly. Chelsea fielded a strong side captained by John Terry and including Branislav Ivanovic, Nemanja Matic, Willian, Ruben Loftus-Cheek and Diego Costa.
