#1 Eden Hazard
Chelsea failed to qualify for the Champions League for the 2nd time in the last 3 seasons. This shows what kind of a mess the Chelsea board are in, even with players of the quality of Eden Hazard, Willian, Kante and Azpilicueta in their squad.
The Belgian is now 27 and at the prime of his career. With his quality, he needs to be playing in the Champions League on a regular basis.
With his current form under Sarri, it seems unlikely Chelsea will miss out again. But this season, the absence of a player like Hazard is just a loss for Europe's most prestigious competition.
