Arsene Wenger has omitted Mesut Ozil from the Arsenal matchday squad to face West Bromwich Albion at The Hawthorns on Sunday.
The Germany international, who started in the Gunners' 3-2 win over Crystal Palace on Thursday, is replaced in the starting XI by Alex Iwobi.
Olivier Giroud and Nacho Monreal are expected to be absent until mid-January, owing to respective hamstring and ankle injuries, while Aaron Ramsey is also struggling with a hamstring problem.
Likewise, West Brom manager Alan Pardew makes one change from the side that started in the 0-0 draw against Everton.
Salomon Rondon, who injured his hamstring in the Boxing Day encounter, drops out of the squad and sees his place taken by Hal Robson-Kanu.
West Bromwich Albion: Foster; Dawson, Hegazi, Evans, Gibbs; Phillips, Livermore, Barry, Brunt; Rodriguez, Robson-Kanu
Subs: Nyom, Yacob, Myhill, McClean, Burke, Krychowiak, McAuley
