One of the greatest frustrations of the 2021/22 season for Thomas Tuchel was the lack of adequate wing-back cover when both Ben Chilwell and Reece James went down injured.
In a brief period when both were fit and starting between October and November, Chelsea flowed brilliantly, swatting opponents aside and overwhelming defences in part due to the movement of the wing-backs.
Once both went down and Tuchel had to use Marcos Alonso and Cesar Azpilicueta instead, the tempo of passing and the quality of service went down. Resolving that issue this summer is crucial, especially if Tuchel aims to keep using wing-backs.
