The 23-year-old has impressed for Chelsea since joining from Lille in 2012 – scoring 31 times in 114 games for the Premier League club.
"I'm not a top-five player yet. Maybe I'm close to it, but I still have to work on some aspects," he told reporters.
"You can only be part of that group if you are decisive in the top games. I start doing that, like I did against Manchester City and Arsenal.
"Who are better than me? The two extra-terrestrials, Ronaldo and Messi, [Zlatan] Ibrahimovic, [Franck] Ribery and [Arjen] Robben. They make the difference almost every game."
Hazard has scored twice for Chelsea thus far this season.
