Substitute Gabriel Martinelli scored a dramatic stoppage-time equalizer as Arsenal drew 1-1 with Manchester City.
Erling Haaland gave City the lead in the ninth minute with a goal on the counter-attack.
Despite a frustrating first half for Arsenal, second-half introductions of Bukayo Saka and Eberechi Eze immediately energized the team.
Just as it seemed City would hold on, Martinelli, assisted by Eze, lifted a finish over the goalkeeper in the 93rd minute to rescue a point for the Gunners.
The result leaves City eight points behind league leaders Liverpool after five games.
