Maurizio Sarri believes Eden Hazards biggest problem at Chelsea is failing to understand the importance of scoring goals and providing assists.
Hazard has been Chelseas star man under Sarri and the Italian has already backed the Belgian to score 40 goals this season.
The 27-year-old is widely considered as one of the best dribblers in the world but has been criticised for not being prolific enough in front of goal.
And Sarri believes that Hazard has been restricted because his main aim has been to have fun on the pitch.
Hazard is immense and I dont think even he knows how much he can still improve, Sarri told Corriere dello Sport.
I said he could end up in the tight circle of the best three or four players in the world.
The problem is he plays to enjoy himself and at times doesnt realise the importance of moving from fun to reaping the rewards.
At the end of the day, youve got to get the fruits of your labour.
Hazards approach is a positive, but it can become a potential limitation too.
He needs to lift his head up, look around and realise theres a whole world in front of him that he can dictate with his feet for the good of the team and not just the individual.
