Arsenal let a two-goal lead slip against Liverpool last time out to draw 2-2.
Gabriel Martinelli and Gabriel Jesus put the Gunners ahead at Anfield before Mohamed Salah halved the deficit shortly before half-time. Salah then missed a penalty that would have drawn Liverpool level but Roberto Firmino put Jurgen Klopp's side on terms with three minutes to go.
Aaron Ramsdale made a superb save late on to deny Ibrahima Konate and end up saving Arsenal a point and preserving a six-point advantage over City in second in the Premier League. City made light work of Southampton on Saturday evening, beating Ruben Salles' side 4-1 to keep up the pressure on the Gunners.
