DC: Laurent Koscielny
A solid performance considering it was his first game back from injury, Laurent Koscielny did well at the back for Arsenal as they kept a clean sheet. 7/10.
DC: Per Mertesacker
Better with Koscielny alongside him, Per Mertesacker did well to weather a late West Brom storm as Arsenal ground out a hard-fought victory. 7/10.
