"The victor of Belgium v France will be the firm favourites to win a World Cup that has made for compelling viewing from first to last", he added.
Speaking to beIN sports, the 27-year-old said: "I have said 100 times before I am happy at Chelsea, but we will see what happens".
Chelsea superstar, Eden Hazard, has continuously been linked with a potential move to Real Madrid and has been touted as the ideal long-term replacement for an ageing Cristiano Ronaldo.

Those participating in cleanup efforts should be careful with heat strokes, as the next few days are expected to be hot and clear. Prime Minister Shinzo Abe cancelled his planned July 11-18 trip to Europe and the Middle East to oversee the emergency response.
But Hazard believes Madrid are still an attractive destination for any footballer in the world, even without legend Zidane at the helm.
World Cup knockout football is not easy, but we have a great atmosphere and this team never gives up.
Twenty years on, he's just two games away from matching Zidane's feat.
"I might be interested in Real Madrid; they know what they have to do", he admitted back in April.
Asked about his feelings if he could not move to Madrid, he said "The blue sweater (of Chelsea) suits me well, so it does not bother me if I stay". France vs Belgium will be interesting.
