The Mikel Arteta team won comfortably at the Emirates, extending their decades-long domination over the visitors, thanks to a combination of reasonably clinical finishing.
With Aubameyang absent from the team, the Gunners had to rely on other sources for their three goals – a total that could have been doubled if they hadn’t struck the post twice and had one goal disallowed for offside.
Southampton will be unhappy that their early radiance faded so soon after conceding the opener, and the game was effectively over by the time the second goal was scored shortly before half-time.
Southampton will have little time to ponder on their disappointing loss as they prepare to travel to Crystal Palace on Wednesday night.
While Arsenal will attempt to reclaim the momentum they’ve lost in recent weeks by defeating West Ham in a tightly contested London derby.
