Arsenal missed the chance to go four points clear at the top of the Premier League table, as they stalled to a 1-1 draw with Southampton.
Granit Xhaka gave the Gunners the lead on 11 minutes, as he neatly tucked home Ben White's cross. But Mikel Arteta's men were pegged back in the second half through Stuart Armstrong's equaliser, giving Ralph Hasnehuttl and co a valuable point in their bid to avoid another relegation battle.
Arsenal were course for nine successive wins in all competitions, having started the day one point ahead of champions Manchester City. The Gunners headed to the south coast off the back of a hard-fought 1-0 victory over PSV Eindhoven in the Europa League.
