#3 Willian
Due to the bad form of his strikers, Sarri has deployed Eden Hazard as the centre-forward, with Willian and Pedro Rodriguez as his partners on the wings.
Sarri did a lot of work this summer to convince Willian to stay at the club. However, the Brazilian is nowhere near the player Sarri wants him to be. He has only 2 goals in the Premier League this season, which tells a lot.
Chelsea fans have been calling for his benching, and now they have more reasons with Callum Hudson-Odoi waiting for his chance. The young English talent produced a piece of magic on Saturday in the FA Cup, with 2 assists for Alvaro Morata.
Because of Willian's poor performances throughout the season, it's a perfect chance to give Hudson-Odoi more playing time, and convince him that he is the future & the present of the club.
