Two second-half goals consigned Everton defeat at Southampton and prevented Marco Silva’s side from closing the gap on the sides immediately above them in the Premier League table.
Gylfi Sigurdsson side footed in after Kurt Zouma smuggled the ball to the Icelander on 90 minutes but Everton could not recover the deficit they faced following a strike from James Ward-Prowse and Lucas Digne's own goal.
Sigurdsson had forced Alex McCarthy into a flying stop shortly after half-time and defender Jan Bednarek threw his body in the way of an Ademola Lookman drive on 21 minutes.
