#2 Eden Hazard
The fear of Eden Hazard approaching your box is the beginning of heart palpitations.
As crucially important as Jorginho is to Maurizio Sarri, there's only so much orchestration he can do from the middle of the park, and Hazard's unimaginable footwork in the final third, not Jorginho's passing, is what makes the net bulge in Chelsea's favour.
In previous regimes, the Belgian saw less of the ball than he sees now. Mourinho and Conte's predominantly conservative approach limited Hazard's threat to counter-attacks as Chelsea rarely ever controlled games.
Things are different now, the Blues have more possession of the ball, which invariably means Hazard gets more supply and has an unrestrained liberty to influence games like never before; Against Huddersfield, and against Arsenal, the Belgian playmaker came on as a sub and still did serious damage.
Thus far, he's played all four of Chelsea's Premier League fixtures and he's had a telling impact on all; twice as a sub, twice in the starting eleven. Enough said.
