Pep Guardiola looked like he didn’t know what had hit him. As Brighton’s players and supporters wildly celebrated Matt O’Riley’s winning goal, the Manchester City manager must have been contemplating an experience he has never had in almost 20 years as a manager.

A fourth consecutive defeat for the first time in his career will have been especially hard to stomach given how much his side had dominated Brighton in the first half. But a stunning turnaround by Fabian Hürzeler’s side was sparked by João Pedro, who equalised Erling Haaland’s opener before setting up fellow substitute O’Riley five minutes later.
