They can also look at Antonio Conte who is vacant. He is a good tactician and will help these talented players.
Conte would absolutely be a great choice. Maybe even the best one. Because as you know Conte already has a history with Chelsea. He made Chelsea Premier League and FA Cup champions once each.

.
Conte to Chelsea in this era is the wrong move and that will definitely send Chelsea closer to relegation; the squad is very younge and also expensive; Chelsea needs a good tactician and great manager to manage the squad, nagglesman comes to mind tbh
Conte won’t fit well at all
