A strong Southampton side knocked holders Arsenal out of the FA Cup in the fourth round courtesy of a first-half own goal on Saturday.
The Saints were rewarded for their attacking intent in the opening period when Gabriel turned in Kyle Walker-Peters' cross in the 24th minute.
It was the first goal Arsenal had conceded in 508 minutes as they suffered a first loss in seven matches.
Southampton will face another Premier League side, Wolves, in the next round.
With their next opponents enduring a poor run in the league and having struggled in their 1-0 win at non-league Chorley on Friday, the 1976 winners will fancy their chances of progressing further at Molineux.
