Chelsea ace Eden Hazard has declared N'Golo Kante the best midfielder in the world.

But Hazard also insists Kante needs to make the most of his new role in manager Maurizio Sarri's system.

"N'Golo is a smart player, one of the best in his job, if not the best in the world," he told The Times.

"N'Golo has been playing for six months in different positions. He needs to adapt. When we win, everyone says, 'Yes, he plays his favorite position', and when we lose everyone says, 'No, he has to play deeper'.

"Everything depends on the result."
