Arsenal were given a lesson on how to play football by Southampton for the second time this season as they ran Arsene Wenger's men ragged at St Mary's Stadium on New Year's Day.
It was the fifth defeat Arsenal have suffered this season in the Premier League and, while no one in the Gunners team impressed, both goals came at the fault of goalkeeper Wojciech Szczesny.
Sadio Mane was tussling for the ball with Laurent Koscielny on the edge of the box in the 34th minute before Szczesny rushed out eccentrically. Mane turned away and finished with an impressive lobbed effort from a tight angle.
Poor decision making
Unfortunately for the Polish goalkeeper, the second goal also came as a result of poor decision making. A cross came in which Mathieu Debuchy cut out with a loose but effectively touch.
Before he could clear it properly, Szczesny slid in with an unnecessary and terrible clearance which fell straight to Dusan Tadic, who had the easy task of slotting home to make it 2-0.
Playing up front, Alexis Sanchez looked isolated and Arsenal failed to cut out a clear chance at any point during the game. The defeat leaves Arsenal trailing well behind the title race and fighting to get back into contention for a familiar top four spot.
The nightmare was complete for Arsene Wenger after a fan stormed onto the pitch to confront him face to face. He got a couple of choice words in before stewards managed to catch him. More controversy ensues...
