Relegated Southampton made the perfect start to life back in the English Football League thanks to substitute Che Adams' late winner at promoted Sheffield Wednesday.
The visitors took an early lead when Nathan Tella cut in from the right and unleashed a fine left-footed shot from the edge of the area that took the smallest of flicks off the back of Adam Armstrong's head on its way past Owls goalkeeper Cameron Dawson.
The home side, who had been utterly outplayed in the first half, levelled after the break when Lee Gregory smashed home after a corner was headed back across goal.
