A relatively tight encounter with Leeds United at Wembley Stadium - just 24 hours after the Reds had beaten arch rivals Manchester City in the FA Cup final on the same turf - saw the Saints go marching on into the top flight for next term, with their slender 1-0 triumph enough to seal the deal.
Forward Adam Armstrong made the difference on the day, slotting home a calm first-half finish after taking advantage of a disjointed Leeds backline.
That goal was enough to confirm Southampton's Premier League status for next season and means that the competition's full line-up is now known.
