Danny Ings scored his seventh of the season to cancel out Mason Holgate’s opener, but Richarlison sublimely finished on the volley 15 minutes from full-time to give Everton a 2-1 Premier League win.
Southampton slipped to 19th in the league table joint with Watford, but below the Hornets on goal difference through 12 matches played.
Yerry Mina and Djribril Sidibe narrowly avoided giving away penalties, with the former escaping what could’ve been a stonewall call if VAR had come into play.
James Ward-Prowse had the chance to put Saints ahead, but could only sting the gloves of a diving Jordan Pickford from the ensuing free-kick.
Richarlison then met Sidibe’s long cross from the right on the volley to give Everton a 2-1 lead, which was enough to secure all three points.
