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.
"It is not frustrating, but disappointing," the Saints boss said. "Over the 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 and again we should have been more aggressive.
"We practically nullified Stoke in the second half and were creating all the chances but in the end it was not to be."
