#3 Chelsea
Chelsea have looked resurgent under Maurizio Sarri and the Italian's attractive "Sarriball" is at full display. There was a lot of skepticism surrounding Chelsea at the start of the season as they had hit the reset button once again and were starting with a new coach in Maurizio Sarri. Though the Blues have been impressive and are the only unbeaten team in Europe's Top Flight, they do have some flaws.
Maurizio Sarri has helped us out in pointing out this one. The Defence. Though the backline consisting of Marcos Alonso, David Luiz, Antonio Rudiger, and Cesar Azpilicueta has been pretty solid on paper, they have looked shaky at times. Sarri demands a lot from all his defenders, offensively and defensively and it's one aspect they can definitely improve on.
Alvaro Morata has looked better this Season for the West London outfit but is too inconsistent while Olivier Giroud sets up more goals than he scores. Though Chelsea are getting Goals from Eden Hazard, Ross Barkley and Willian, Sarri will want his strikers to contribute more.
