Oleksandr Zinchenko thanked fans at the Etihad Stadium after making his first return since leaving Manchester City.
The Ukraine international joined Arsenal over the summer in a deal worth up to £32m. His former City colleague Gabriel Jesus also moved to north London, and the pair have helped put Mikel Arteta's team in contention for a first league title in 18 years.
City and Arsenal have yet to meet in the league this season, but Pep Guardiola's side won the first clash between the sides in the FA Cup on Friday night. Zinchenko appeared to get into an altercation with his former teammates in Manchester but made his feelings clear after the game.
