Everton boss Roberto Martinez was left disappointed with their defending for defeat at Southampton.

All of the home side's goals were scored as a result of crosses into the Blues' penalty area.

Martinez said: "The most disappointing thing was the way we defended our box. We were a little bit soft and were undone by three balls that went into the six-yard box.

"We are to blame for the defeat because we didn't defend any simple ball into the box well. Our record shows that we are normally a lot better in that respect and that is where we lost the game.

"The second half we started with a good mentality and we had Southampton where we wanted them. All they wanted to do was work on the counter-attack.

"But it was disappointing to concede three goals the way we did. Clearly it was a day when nothing went in our favour because even when we created opportunities we never hit the back of the net. The difference between the two sides was in the boxes."
