Southampton took an early lead when Stuart Armstrong met James Ward-Prowse’s corner with a thunderous half-volley in the third minute, but Nicolas Pepe drew Arsenal level five minutes later with a cool left-footed finish from Granit Xhaka’s pass.

Saka put the Gunners ahead six minutes before halftime, latching on to a superb pass from Lacazette before rounding keeper Alex McCarthy, who had rushed out of his goal, and slotting the ball home.
The roles were reversed in the 73rd minute as Saka crossed for Lacazette to score the third and seal a victory that lifts Arsenal to eighth place in the table on 30 points, one ahead of Aston Villa, Chelsea and Southampton.
