Southampton manager Claude Puel was disappointed his side conceded so late after taking the lead in a 2-1 defeat at Arsenal on Saturday.
A Petr Cech own goal put Saints in front after 18 minutes, but, after Laurent Koscielny levelled on 29 minutes, Southampton's confidence appeared to take a hit.
Santi Cazorla's penalty -- deep into stoppage time after substitute Olivier Giroud was brought down in the box by Jose Fonte -- was the third Southampton have conceded so far this season in just four games and Puel is not happy with that statistic.
"I am angry for my players," Puel said. "I don't like to speak of the decision of the referee, but we have conceded, in four games in the championship, three penalties.
"I want to stay with the positives of this game. I think we played fantastic in the first 30 minutes.
"We played with good possibilities, we scored. Perhaps at the end of the first half we dropped back, but it was a good game and my players have been bright.
"We had [chances] to score and win this game against a good team and a draw would have been a [reward].
"It is a disappointment for my players to lose this game in this condition."
