Eden Hazard believes Chelsea teammate Diego Costa is 'sharp' in his game at the moment.

The Spaniard has scored five goals in as many Premier League outings so far this season which has attracted praise from star playmaker Hazard.

The Belgian told Chelsea TV of his Blues colleague: "Diego is a top player, he is on the pitch to score goals, he has the desire to score a goal every game, and it's always good to play with him.

"He's sharp."

Hazard and Costa will be in action when Antonio Conte's Chelsea travel to the King Power Stadium to take on reigning Premier League champions Leicester City in the EFL Cup third round on Tuesday night.
