Southampton head coach Jan Poortvliet blamed his side's woeful start for Monday's 3-0 defeat at Crystal Palace.
The Saints never recovered after Shefki Kuqi and Craig Beattie had netted inside the opening 15 minutes to leave the visitors hovering just above the drop-zone.
Poortvliet said. "We didn't start sharply and waited until we were two goals behind until we started playing, but even then I never thought that we looked like scoring.
"I told them in the dressing room after the game that even if we played on for a whole week we still wouldn't score if we played like that.
"We know that the boys can do it but we always have to motivate and push them each time because that is not coming from them.
"That's a shame, because when you play professional football you have to show that each time."
