Belgium coach Marc Wilmots says Chelsea star Eden Hazard must improve his finishing.

Wilmots insists Hazard can only rival Lionel Messi and Cristiano Ronaldo if he improves his finishing.

"Eden is progressing at an excellent rate for the moment, and I hope he is ambitious to reach that level," Wilmots told FIFA.com.

"He just needs to be more clinical and improve his finishing.

"He showed at Lille that he could score 20-odd goals a season, and that's where he needs to improve in order to help his team out at key moments.

"But it's also about how a team plays which makes that possible. Eden is still young - he's 23 and he has lots of ambition, which is good. I wish him all the best with it."
