Southampton manager Ralph Hasenhuttl branded Liverpool's equaliser 'a pity' as his side fell to a 3-1 defeat at St. Mary's.
The Saints' bright start was rewarded with Shane Long's goal on nine minutes, but the hosts went into half-time level as Naby Keita headed home his first ever goal for Liverpool.
Second-half strikes from Mohamed Salah and Jordan Henderson meant Hasenhuttl's side suffered their sixth home league defeat of the season.
The Austrian however was disappointed with Liverpool's route back into the game, claiming Salah was offside in the build-up to a goal that helped changed the course of the game.
