Manchester City stumbled again in the battle to secure a return to the Champions League as they were pegged back twice by fellow top-five challengers Brighton in an entertaining encounter at Etihad Stadium.

Erling Haaland became the first player to reach 100 Premier League goal involvements in fewer than 100 games when he marked his 94th appearance in the competition with his 84th goal by sending Brighton keeper Bart Verbruggen the wrong way with his 11th-minute penalty.
