Chelsea boss Maurizio Sarri says Eden Hazard can be the best in the world - if he wants to.

Sarri's predecessor, Antonio Conte, complained the 27-year-old, for a player of his talents, did not score enough goals.

Last season he managed 12 in the Premier League but Sarri said it was now up to Hazard to raise his game to become a true great.

“Eden can improve," said the Italian. “We are talking about one of the most important players in Europe now but, in my opinion, he can improve more.

“He can be the first (in the world). It depends on him. The best for technical skill, the best for scoring, but I think it depends only on him. On his mind."
