Portsmouth boss Harry Redknapp was left to rue mistakes at set-plays after his side lost their derby at Southampton.
"We should have taken something from the game but we got punished from set-pieces," he said of the 2-1 defeat.
"For the second goal we didn't pick up Kevin Phillips. Arjan De Zeew is normally magnificent but he went to sleep and it cost us the game.
"The game could have gone either way and we conceded both goals while we were on top but that's how it goes."
