DANNY Shittu says Millwall have to put their collapse against Birmingham City behind them as they prepare to face Huddersfield Town at The Den on Saturday.
Shittu revealed he was left feeling "shocked" after the Lions threw away a three-goal lead against the Blues, but says the players can not afford to dwell on the result.
But he admitted he was "gutted" to have slipped in the build up to Marlon King's first of three goals on the stroke of half-time, which swung the momentum in the visitors' favour at a crucial point of the match.
"The players have been in shock after what happened the other night," he told Lions Live. "The whole team was shocked we allowed something like that to happen.
"It's something that, personally, has never happened to me before. I just slipped over as I went to mark Leroy Lita.
"He shanked the shot and it's gone to King to tap in. We were gutted to give away a goal just before half-time.
"That's the thing about being a defender. When you're a striker, you score one goal from a few chances and you're a hero.
"As a defender, you can do nine things right but when you make one mistake, it stands out. We take that on, being defenders.
"We went into training on Thursday and we spoke about it because after games like that, you do have to look at things you did wrong so they don't happen again.
"But we've got a big game on Saturday and we can't let something like that affect us. We've got to pick up the positives and put it right.
"That's what the gaffer and the backroom staff have been saying and we believe we can go out and win. We're working towards a clean sheet and the gaffer has gone on about it a lot.
"I don't fear any of Huddersfield's strikers and nor do the rest of the team. We're going to go out there and do what we're good at, and hopefully I won't slip over again."
