The Blues' top goalscorer this season has been in blistering form in 2013-14, notching 11 times in 34 matches as he flourishes under Jose Mourinho, but accepts that reaching the top level will prove no easy feat.
"I realise that I can compete with Messi and Ronaldo in the near future, if I put in some more effort," the £32 million man told Het Laatste Nieuws.

"Previously I was more worried about the game itself: Football was just a game for me - I wanted to amuse myself and didn't bother what the people thought about me - but since I've been here at Chelsea I've become more aware of my qualities, I guess.
"Before I knew I was a good player but not one of the better players in the world.
"I've matured," Hazard continued. "On the pitch I haven't changed much, I'm still the same, but I realised that, if I want to be among the best in the world, I'll have to perform consistently, game in, game out.
"I'm now important for the team, I give good passes, I score more goals and Chelsea are performing well.
"Everyone expects more from me. I hear it every day. Maybe I need these little comments, too."
