City defender Pablo Zabaleta is set to switch flanks to play at left-back. City are without regular left-backs Gael Clichy (suspended) and Aleksandar Kolarov (groin) so Zabaleta will move across with fit-again Micah Richards returning at right-back. Richards has missed the last two games with a calf problem. City boss Roberto Mancini has no other injury concerns. Arsenal have no fresh injury worries. Full-back Kieran Gibbs is recovering well from his hernia problem, and could feature over the Christmas period and midfielder Jack Wilshere remains on course for a mid-February return from his ankle injury. Defenders Andre Santos (ankle), Carl Jenkinson (back) and Bacary Sagna (ankle) remain out, along with goalkeepers Lukasz Fabianski (knee) and Vito Mannone (shoulder), and midfielders Abou Diaby (hamstring) and Ryo Miyaichi (ankle). Man C (from): Hart, Richards, Lescott, Kompany, Savic, K Toure, Zabaleta, Milner, Johnson, De Jong, Barry, Y Toure, Hargreaves, Silva, Nasri, Dzeko, Balotelli, Aguero, Pantilimon. Arsenal (from): Szczesny, Vermaelen, Mertesacker, Koscielny, Djourou, Song, Ramsey, Arteta, Walcott, Gervinho, van Persie, Almunia, Miguel, Benayoun, Frimpong, Arshavin, Chamakh, Coquelin, Rosicky, Oxlade-Chamberlain.
