Son Heung-min's late penalty capped a Tottenham fightback against Southampton that handed interim head coach Ryan Mason victory in his first match in charge.
He made a winning start to his tenure after Gareth Bale curled in a superb equaliser and then a late VAR intervention saw Son convert after a Moussa Djenepo foul on Harry Winks was shown to be just inside the penalty area.
Until Bale's composed finish on the hour mark the hosts had been second best to a slick Southampton side who went in front when Danny Ings glanced in James Ward-Prowse's corner.
