With Johan Djourou injured, Coquelin will deputise at right-back. That means Laurent Koscielny and Per Mertesacker will continue at the heart of defence, with Thomas Vermaelen in once more at left-back.
Wenger has kept faith once more with the same trio in attack, as Theo Walcott, Gervinho and Robin van Persie all start in the West Midlands.
Team in full: Szczesny, Coquelin, Mertesacker, Koscielny, Vermaelen, Frimpong, Arteta, Ramsey, Walcott, Gervinho, Van Persie.
Subs: Almunia, Squillaci, Benayoun, Arshavin, Rosicky, Oxlade-Chamberlain, Chamakh.Copyright 2015 The Arsenal Football Club plc. Permission to use quotations from this article is granted subject to appropriate credit being given to www.arsenal.com as the source 21 Dec 2011
