#2 Jorginho
Chelsea's top signing of the window, Jorginho may be the heart of Chelsea's midfield next season. The Blues had a strong interest in the Italian midfielder as they looked to rope in Sarri as Antonio Conte's successor.
Jorginho played a key role under Sarri last season at Napoli as the club finished as runners-up in Serie A. However, the central midfielder's role may be modified at his new club, different to the one he played at the Naples-based club.
He played as a defensive midfielder at Napoli but that role is already occupied by Kante at the London club. If the Chelsea board succeeds in keeping Kante at the club, Jorginho's role may be different. Jorginho, who is a box-to-box midfielder, may play as deep-lying play-maker, similar to what Kevin De Bruyne plays at Manchester City.
