Ozil double makes Arsenal remain top, Southampton hold United

Mesut Ozil scored twice as a second-half burst earned Arsenal victory over Norwich to extend their lead at the top of the Premier League.
The Gunners looked lethargic after the international break but Jack Wilshere volleyed in a superb opener before Ozil's header appeared to settle it.
Jonny Howson found the bottom corner with 20 minutes left to fray nerves.
But Aaron Ramsey scored a lovely ninth goal of the season to make it 3-1 before Ozil grabbed an easy second.

Manchester United dropped two points as Southampton scored a late equaliser to claim a dramatic draw at Old Trafford.
The hosts took a first-half lead when Robin van Persie followed up to score after Wayne Rooney's effort had been blocked by goalkeeper Artur Boruc.
United hit the crossbar twice, through a Rooney shot and a van Persie header.
But their failure to kill the game off proved costly when Southampton grabbed a last-minute leveller, Dejan Lovren bundling in James Ward-Prowse's corner.
