RONALD KOEMAN says an uncharacteristically poor defensive display cost his side as Crystal Palace stunned Southampton on the south coast.
The Eagles scored three goals against the Premier League's meanest defence to dump the Saints out of the FA Cup at the fourth round stage, with all the goals coming in the first half of the clash.
And the Saints boss said he was disappointed with the unusually poor display defensively from his side.
"If you talk about defensive organisation, it is normally one of the strengths of the team," he said.
"But not today. We were not working together and the spaces between the players was too big.
"Crystal Palace punished us to score three goals, but defensively we were very poor and you cannot defend like that.
"Second half we were a bit better, but not good enough to get a draw and the bad first half is why we have lost the game.
"You cannot concede like that twice, so soon after taking the lead, and we were just very poor defensively."
