Southampton manager Ronald Koeman was disappointed after his side's hopes of fifth spot were hit hard by a 2-0 defeat at Leicester.
Koeman said he had been impressed by Leicester's spirit, but also admitted his side were off the pace.
"We knew what Leicester did last week, scoring an early goal, but we had problems at the beginning," said the Saints boss.
"There was a lack of sharpness. Leicester started confidently and were aggressive. They had two chances and scored two goals.
"That makes it difficult, and that is why we lost today -- no sharpness at the start of the game.
"We didn't create a lot. We changed things in the second half a bit but it was difficult -- good organisation and positioning from Leicester.
"Leicester we're full of confidence and had a cause. They were fighting for something. Fighting against relegation. Fighting for their lives.
"We didn't have that in our play, there was too much doubting in our side."
