The Gunners have overcome a defensive injury crisis over the past few weeks to maintain their undefeated record, which now stands at nine Premier League games. Although they had several absences, but still looked Hector Bellerin, Sead Kolasinac and Nacho Monreal Laurent Koscielny had received after his injury from last season a new blow with the horror injury of Danny Welbeck on Thursday night.
