Arsene Wenger has made three changes to the side that drew against West Bromwich Albion last weekend as Arsenal prepare to host Chelsea at the Emirates.
Mesut Ozil is the biggest name returning to the starting lineup after recovering from a knee injury. The German playmaker has replaced Alex Iwobi, who returns to the bench. Sead Kolasinac and Laurent Koscielny are the major absentees after picking up injuries over the weekend.
