N'Golo Kante covers so much ground on the pitch his Chelsea team-mate Eden Hazard is starting to wonder whether he might be secretly playing with a twin.

Kante has been a revelation since his £32 million ($39 million, 37 million euros) move from Leicester City last year, his all-action displays helping Chelsea go 10 points clear in the Premier League.

Kante starred in Chelsea's 2-1 win at West Ham United on Monday, with his interception starting the move that led to Hazard's opener, and the Belgian was quick to praise the France midfielder's display.

"I think sometimes when I'm on the pitch I see him twice -- one on the left, one on the right. I think he plays with a twin," Hazard told Chelsea TV.

"I don't need to say something about N'Golo. Everyone knows about him. He's everywhere."
