Southampton eliminated holders Arsenal out of the FA Cup thanks to an own goal from Gabriel at St Mary’s Stadium.
Former Tottenham full back Kyle Walkers-Peters drove a low effort towards the far post which the Brazilian tried to block but only succeeded in diverting past Bernd Leno.
The Saints dominated the first hour of the match, with Arsenal struggling to beat their high press, and could have been further ahead with James Ward-Prowse freakishly hitting the bar from an errant corner and Che Adams forcing a good save from Leno after an inspired run cutting in from the right flank.
The introduction of Thomas Partey, Bakary Saka and Alexandre Lacazette saw the Gunners come to life in the last third of the game, but overall the hosts were worthy winners.
The south coast outfit will now host Wolves in the fifth round in three weeks’ time.
