Davide Zappacosta has talked up the training exploits of Chelsea teammate Eden Hazard.

The Belgian has taken his game to another level this season under Maurizio Sarri.

And Zappacosta has revealed he does not take his game lightly against his Blues teammates either.

"[He is also] the best player in training," the Italian said of Hazard, via the Daily Star.

"He's almost unstoppable, especially for the defenders when you have to mark him.

"It's a hard job because he's very quick and he has excellent quality, so it's not simple to stop him."
