Wigan Athletic boss Roberto Martinez accepted that his side had deserved nothing from their 2-0 weekend defeat at Fulham.
The Latics were previously unbeaten away from home this season and Martinez is confident that the display at Craven Cottage will not be repeated.
The Spaniard commented:"That felt like our worst performance of the season and we didn't deserve anything out of it.
"We came here with no real energy. We looked flat, couldn't get on the ball and were very weak.
"Fulham were sharper and brighter. It was one of those performances that we must eradicate from our season.
"I'm not worried about being dragged down into the relegation struggle. I know the talent and personalities I have in this squad.
"We need to be realistic. Against Fulham we weren't good enough and there are reasons for that.
"We have to make sure it doesn't happen again. Until yesterday we were the only team that hadn't lost away."
