LONDON -- Eden Hazard must work harder in training if he wants to be the world's best player, according to head coach Maurizio Sarri who believes Chelsea have only seen "75 or 80 percent" of the forward's potential so far.
Hazard has made a blistering start to the season by scoring seven goals in his first eight Chelsea appearances in all competitions, including a spectacular solo strike to eliminate Liverpool from the Carabao Cup in Wednesday's third-round tie at Anfield. Such displays have led many to suggest that the Belgium international is ascending to the level of Lionel Messi and Cristiano Ronaldo.
