Ronald Koeman well and truly disproved the manager of the month hoodoo as his Southampton side decimated a woeful Sunderland outfit 8-0.
There is a longheld theory that the boss who collects the monthly accolade slips to defeat in the next game but Saints returned to winning ways with their biggest ever Barclays Premier League win as Graziano Pelle scored twice to seal a memorable week on a personal level.
A goal in either half saw Pelle move onto six Barclays Premier League goals for the season and add to his match-winning Italy debut and player of the month award.
The former Feyenoord striker would have been proud of Vergini's own goal, which opened the floodgates as Southampton inflicted a damaging defeat on Gus Poyet's side.
Sunderland had started the game brightly as they looked to build on their maiden league win against Stoke before the international break but Vergini scored a clinical own goal from the edge of his box to set Southampton on their way to a stunning victory.
Pelle then scored with a tap-in with Jack Cork, brought into midfield in place of Victor Wanyama, killing the game off before the break.
Sunderland then shipped four goals in 16 second-half minutes as a another own goal, courtesy of Liam Bridcutt, was added to by Pelle's second and efforts from Dusan Tadic and Wanyama.
Sadio Mane had been rested following international exertions but came on to add the eighth late on, leaving some Sunderland fans in tears.
Saints may boast the player of the month in Italian striker Pelle but they also have the best defence in English football having conceded a measly five league goals this season.
Sunderland's defence is not as watertight and it starting leaking goals after just 11 minutes as Morgan Schneiderlin eased past Wes Brown, with the ball falling to the edge of the Sunderland box, where Argentina international Vergini thrashed the ball into the corner of his own goal with deadly accuracy.
It did not take the hosts long to double their lead as Steve Davis was released down the left and crossed for Pelle to tap home from close range to continue his impressive form.
Shellshocked Sunderland looked like they might peg their hosts back immediately but goalkeeper Fraser Forster was equal to a well-struck Sebastian Larsson free-kick.
Poyet was left angered when his side were denied what appeared to be a clear penalty as Forster cleaned out Steven Fletcher after the Scotland forward had latched onto Lee Cattermole's through ball - but referee Andre Marriner simply signalled for a goal-kick.
The Uruguayan's mood was not helped as Southampton added their third from the very next attack. Tadic crossed from the left and picked out an unmarked Cork, who got enough on his shot to force it past Vito Mannone.
Pelle should have done better with a chance on the stroke of half-time but cut his effort well wide of goal as Saints continued to dominate.
Southampton came close to extending their lead early in the second half as Shane Long squared to Tadic inside the box, but the Serbia winger saw his shot cleared off the line by Patrick van Aanholt.
Sunderland boss Gus Poyet has heaped praise on Southampton ahead of Saturday's Premier League clash at St Mary's Stadium.
The Saints sold five first-team players and replaced them with several others during the summer. Former manager Mauricio Pochettino also departed and was replaced by Ronald Koeman, leading to many pundits predicting that the club might struggle this season.
However, Southampton are 3rd in the Premier League table after winning four of their opening seven games.
Sunderland boss Gus Poyet is happy for John O'Shea after the Irishman had a good week for both club and country.

Sunderland Boss Gus Poyet is refusing to panic, even though his team are still without a premier league win this season.
The Black Cats have only lost once in the league so far, but they're yet to secure their first victory.
Poyet felt his team's performance last weekend in the goalless draw against Swansea was a big improvement though, and he can see much better times ahead.
Sunderland boss Gus Poyet believes Stoke midfielder Steven N'Zonzi should have been sent off during his side's League Cup exit against Stoke.
With the score level at 1-1, N'Zonzi appeared to grab Sunderland's Jack Rodwell by the throat after the two came together in a challenge. Referee Mike Dean showed yellow cards to both players but Poyet felt aggrieved that N'Zonzi wasn't sent off.
The Black Cats lost 2-1 on the night.
Sunderland's dream of another trip to Wembley has been quashed after Stoke beat them at home 2-1 in the third round.
