Ju Young Park will make his Champions League debut in Arsenal colours for the visit of Marseille to Emirates Stadium.
The South Korean international has made two appearances in a Gunners shirt so far - both arriving in the Carling Cup - and will take the place of captain Robin van Persie, who drops to the bench.
Thomas Vermaelen will make his return to European action after featuring in the Gunners' last two fixtures, and is now braced for another outing alongside Per Mertesacker at the heart of defence.
Carl Jenkinson returns from injury to take up his place at right-back, with Andre Santos continuing at left-back.
Team in full: Szczesny, Jenkinson, Vermaelen, Mertesacker, Andre Santos, Song, Ramsey, Arteta, Walcott, Gervinho, Park.
Substitutes: Fabianski, Koscielny, Djourou, Rosicky, Benayoun, Arshavin, Van Persie.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 1 Nov 2011
