Brighton and Hove Albion defeated Manchester City at Amex stadium to condemn Pep Guardiola to a fourth successive defeat for the first time in his managerial career.
It is the first time since 2006 that City have lost four in a row.
The Premier League champions looked on course to end their disappointing sequence when Erling Haaland capped an impressive opening minutes to score at the second attempt from Mateo Kovacic’s pass.
Brighton, however, held their nerve, taking complete control after the break – and it was only their poor finishing that prevented them drawing level before substitute Joao Pedro pounced in a scramble 12 minutes from time.
City, who had looked increasingly vulnerable, were on the rack and Brighton took a deserved lead when Matt O’Riley, who has been out injured since his debut following a move from Celtic, burst through an exposed defence to beat keeper Ederson five minutes later.
