#2 Jorginho Effect
Jorginho has been a great signing for Chelsea, his deep-lying playmaker role is seeming like an absolute asset to Sarri's Chelsea. He completed more passes against Newcastle than the entire Newcastle team. Jorginho made 158 passes in that match alone.
Having also played under Sarri at Napoli means he doesn't need time to adapt to Sarri's philosophy and he fits perfectly into his 4-3-3 system just sitting in front of the back 4. He has also shown us what N´Golo Kanté can do if he is given the license to push forward.
He is only 26 years old and has his prime yet to come, his composure and passing ability can really help Sarri win the English Premier League. As he makes them tick and he is the center point of the team and allows others to play to their strengths.
