Paul Ince's tenure as Notts County manager began in a 3-1 defeat as Southampton came from behind to claim all three points at Meadow Lane.
Ince had barely settled into his seat in the stands when his new charges took the lead, Ben Davies' corner headed home with purpose by Mike Edwards.
And Edwards almost got a second minutes later from another Davies corner as the Saints failed to learn their lesson.
Ricky Ravenhill then saw his volley saved by Kelvin Davis, before a stinging free-kick from Rickie Lambert struck the post and Adam Lallana's long-range drive whistled over the crossbar.
The tables turned in the 68th minutes though as skipper John Thompson was controversially sent off for bringing down Lee Barnard in the area.
Lambert took the penalty and silenced the jeering Magpies fans by slotting low to Rob Burch's right.
Ince's debut went from bad to worse five minutes later as Barnard stabbed home from Lallana's corner, before Lallana turned scorer to complete the turnaround, sending a dipping shot into the far corner with the last kick of the game.
