#1 Maurizio Sarri
No new manager is having a better season in the Premier League than the former Napoli boss, Maurizio Sarri. His instant impact at Chelsea was seen when 'Sarri-ball' took the league by storm.
Under him, Chelsea are still unbeaten in the league and currently stand third in the league table trailing the league leaders Manchester City by four points. His 4-3-3 formation relies heavily on summer signing Jorginho's distribution and a rejuvenated David Luiz is key to the build-up play delivering regular and accurate long balls.
The Blues have the second highest number of goals this season, thanks to the in-form Eden Hazard and now confident-looking Alvaro Morata. The best thing about this new Chelsea team is that the squad is extremely well balanced on the pitch, with the defenders, midfielders and attackers all matching each other's intensities.
Final Verdict - Sarri has truly transformed the team's style and structure. His team is yet to make any mistake and the fact that summer signings have already settled well into the first team bodes well for the future of the club.
