The Belgian star has enjoyed a stellar start to the season, featuring in all 10 of Chelsea’s matches while contributing two goals and three assists, yet feels he still needs to up his game in order to be considered as one of the best.
"I'm not a top-five player yet,” Hazard told the Daily Telegraph. "Maybe I'm close to it, but I still have to work on some aspects. You can only be part of that group if you are decisive in the top games. I (have started) doing that, like I did against Manchester City and Arsenal.
"Who are better than me? The two extra-terrestrials, Ronaldo and Messi, Ibrahimovic, Ribery and Robben. They make the difference almost every game."
The 23-year-old admitted to performing below-par at this year’s World Cup, but is enjoying his good start to his club campaign this season after a short rest following the Mundial in Brazil.
"It all goes well for me at Chelsea," he said. "Maybe this has been the best start in my career so far, although it isn't reflected in the stats. I have played only one bad game - against Aston Villa.
"I've taken a good rest during my holiday, I had a short, but good pre-season and I feel really well.”
Hazard says he has a good relationship with coach Jose Mourinho, who keeps him on his toes.
"Jose Mourinho and I get along well,” he said.
“I've lots of respect for him. He gives me a lot of confidence. After a bad game, he dares to say ‘we have played with 10 today’, but that's it. At moments like that he leaves me alone."
