Southampton have won for the first time since September in the League. Arsenal have lost their first match since August.
It's massive relief for the Southampton players. To take the lead twice, be pegged back, and then to win it at the death against the run of play. Absolutely magnificent. But it wasn't perfect.
From Arsenal's perspective, this is why they're not title challengers - three headed goals, poor defending at times, and the goalkeeper was suspect on the last goal.
