The gunners defender is currently with Kante over on international duty ahead of France’s game with Luxembourg on Saturday.
Kante joined the Blues in the summer of 2016 from Premier League champions Leicester and is on par for the title for the second successive season.
Having played against and alongside Kante, Koscielny knows very well of 25-year-old’s abilities and says there is no better in England at the moment.
“For me he is the best player of the championship,” Koscielny said at a news conference.
“He had the aptitude to adapt in his new club, he had a difficult first month but since the loss to Arsenal, he has progressed enormously.
“When you have a player like that in midfield, who gets a lot of balls back…
“He knows what he can and cannot do.
“He harasses his opponents and gives the ball to his offensive players.”
