Gabriel Jesus' deflected effort eight minutes into the second-half separated the sides, but City should have been more convincing winners as they laid down a marker after losing to Chelsea three times towards the end of last season. The most painful of those came in Porto as Chelsea lifted the Champions League to deny City the crowning glory of the club's rise since an Abu Dhabi takeover in 2008.
Pep Guardiola was fiercely criticised for his decision to start without a natural holding midfielder when the sides last met in May. That error was rectified with the return of Rodri and the Spaniard's poise helped Guardiola's men completely dominate possesion. However, City's lack of a prolific goalscorer to turn that dominance into goals was again exposed.
Chances continued to come and go the other end as Grealish was denied again by Mendy when clean through.
