Southampton boss Ronald Koeman felt they sat off Everton for defeat at St Mary's.

Koeman was unable to mark the occasion with a win, accepting "too much" went wrong in the first half.

"I think we gave them too much space to play, too much space between the lines, and you know if you give Everton that space to play football between the lines then you get difficulties," he said.

"Maybe the best example to tell about what happened in the first half was two times a corner kick and one goal and one chance. You can't do that kind of mistakes on this level.

"Then you know it's very difficult to come back in the game."
