It's been quite a turnaround. At the end of last season, Chelsea's midfield was in a dire state. Cesc Fabregas looked a shadow of himself, and the combined £90m that was spent on Ross Barkley, Tiémoué Bakayoko and Danny Drinkwater looked less useful than if they'd just burned that cash and stuck the ashes in the middle of the park. Maybe with a blue shirt over them.
But that was then. This is now. And now, the Blues' midfield is loaded with young, energetic and technical talents, capable of defending and passing with equal measure. 99.9% of that has been down to El Jefe/Head Honcho/Il Capo himself, Maurizio Sarri.
