#2 Eden Hazard
Hence, it is of utmost importance that Chelsea keep their star man happy. Unlike his compatriot Courtois, Hazard has stated that if his club buys the right players and is ready to play a more adventurous style, he will pledge his future to the Pensioners. Hazard is one of the few world class players that Chelsea currently possess. It may not be completely wrong to state that the importance of Hazard to Chelsea is similar to the one that both Ronaldo and Messi have to Real Madrid and Barcelona.
Perhaps, his importance can easily be delineated by the fact that he was the highest goalscorer for the club last season in a campaign in which Chelsea's forwards failed badly. Hazard scored 17 goals in his 52 appearances for the club last season and replacing him will never be an easy task.
However, with the current turmoil at the club, it is a high possibility that the former Lille forward would leave Chelsea this summer and move to Real Madrid, a club who has been constantly linked with him.
The possible departure of Ronaldo from the Spanish club will pave way for another Galactico and if Chelsea do not address their issues sooner rather than later, that Galactico would be the Belgian magician.
