Martinez was disappointed with Swansea's defending

The Spaniard hit out at conceding four goals to the Blue Square South side who only had five chances all game.

But Martinez insisted the Swans will bounce back. He said: "We only have ourselves to blame.

"If you concede four goals out of five chances, you are not going to win a football game."

"It's a hard pill to swallow especially with all the excitement we have in terms of trying to give something for our fans that they really deserved," he said.

"All the boys are really disappointed. We weren't ourselves in the way we defended and that was going to affect our rhythm going forward.

"To give a 3-0 lead is something that shouldn't happen.

"Sometimes you feel football has got some destiny in it and it doesn't matter what you do, you get punished and in that respect, there are many, many things that are disappointing.

"We really lost this tie at home when we created 24 chances and only scored one goal.

"But I can guarantee you we are going to bounce back and respond in the right way."
