The defender was on target with a volley after the Magpies had made life difficult for the in-form Gunners, who also celebrated Leicester’s draw to move clear at the summit
Laurent Koscielny’s strike means Arsenal start 2016 on their own at the top of the Premier League, after a battling 1-0 victory over Newcastle.
Arsene Wenger’s men began the clash as clear favourites at the Emirates Stadium, but struggled to impose themselves over a determined Newcastle team.
But Koscielny pounced with a close-range volley 72 minutes in to give the hosts three points, moving clear of Leicester City as their title rivals were held to a draw.
