CB: Per Mertesacker – 7
Considering he was up against the waspish and frenetic Sterling, he handled it surprisingly well and didn’t let the England international’s pace affect him.
CB: Laurent Koscielny – 7
Was only caught out once in the first half but is lucky Raheem Sterling and Lazar Markovic contrived to screw up what looked a simple tap-in.
There will be concern over a groin injury that forced him off early in the second half although Arsene Wenger attempted to play down it’s seriousness following the win.
