Saints are sinners.
Tough conditions made for a grizzly encounter at St Mary's, where the visitors twice came from behind to eke out a 2-2 draw.
Saints took an early lead through a wonderful Rickie Lambert free-kick, only to be pegged back by Peter Odemwingie's first goal for Stoke, who had gone 369 minutes without netting away from home before that.
Steven Davis' fortuitous effort saw Saints retake the lead soon after, but they again relinquished control when former Southampton frontman Peter Crouch bundled home.
Saints continually pressed for a winner in the second half but could not find a way through, much to the annoyance of manager Pochettino.
"It is not frustrating, but disappointing," the Saints boss said. "Over 90 minutes we deserved to win but in football you can't really deserve to win you have to show it and do it.
"The only 'but' is that after that [Lambert goal] we were not aggressive enough to go on and get a second and that would have put the game to bed. Then when we went to 2-1 we weren't able to hold on to the lead."
