Guardiola has utilised the services provided by his full-backs very astutely. Benjamin Mendy and Kyle Walker are tactically competent. The pair will look to occupy the midfield to make up for the space left by David and Bernardo Silva as they venture forward with the wingers branching wide. This approach should provide City the edge, if United attempt to press them or play a loose line like they’ve done this season. However, if United opt for a more pragmatic approach and play narrow, the full-backs will look to create overloads on the wing and allow Sterling and Mahrez the freedom to cut inside. The versatility of the full-backs which allows them to execute both roles will be crucial.
