Russell Martin had seen enough before half-time during Southampton's 5-0 loss by Tottenham on Sunday.
The Saints manager stormed off the pitch and into the dressing room at 4-0, only for James Maddison to complete his brace in the fourth minute of additional time in the first half to make it 5-0.
The loss puts Southampton at risk of breaking the most unenviable record a team in the Premier League could.
If they do not tally any points before Matchweek 18, they would mathematically be on track to eclipse Derby's record of achieving the least points in a Premier League season.
