Kevin Foley admits Wolves are under no illusions about the drop in level of their performance at Crystal Palace on Tuesday - and are ready to put things right at Birmingham on Sunday.

The players have sat through a re-run of the cup exit at Selhurst Park in a bid to pinpoint just where things went wrong as Wolves exited the FA Cup in the Fourth Round replay.

The versatile defender believes that's a good way to exorcise the demons of the team's display and to learn from the mistakes ahead of the remaining 15 games of the Barclays Premier League season.

"It was clearly a very disappointing night at Palace," he said.

"It was a crazy spell when they scored their three goals and we'll be looking at it again on the DVD and pointing the fingers at ourselves.

"We look at all the relevant bits and see what went wrong.

"Up until that point there hadn't really been a great deal in the game - it had been quite even with not a lot happening at either end.

"From our point of view we then gave away three sloppy goals and no one was anything other than extremely disappointed with our performance."

Foley also plays down any suggestions that Wolves' midweek problems were caused by the recently changed formation which had already garnered draws against Liverpool and Hull.

"When we played Hull we looked quite dangerous and got players forward well," he said.

"That was slightly different to Liverpool when we looked solid.

"When we use this different formation it's versatile and you certainly can't use that as an excuse for what happened at Palace.

"It's more a case of all of us looking at ourselves as individuals and together as a team and putting things right and moving on.

"You can't just banish the sort of performance we had on Tuesday and try and forget about it.

"You look at it and dissect it with the gaffer and 'TC' and learn from it.

"The key to games like that is to make you sure learn from it and hopefully it will make us all better for doing it."

And Foley knows Wolves will have to be a whole lot better to stand any chance of getting anything from St Andrew's in Sunday's big derby (kick off 1.30pm)

"Birmingham have been going very well - they've had a great season," he said.

"They've become a very hard team to beat with a good defensive record and have got threats going forward.

"They've got some great results this seasons and so we know it's going to be a really tough game.

"Obviously we'll be going in as underdogs because of the way they've been going this season and that might suit us.

"We're certainly looking forward to it and it's a game we are ready for.

"We have shown we can get results away from home and were actually disappointed we didn't win at Hull after creating a couple of chances late on.

"So we won't go Birmingham with any negative thoughts - we'll be going to try and get a result which we're definitely capable of."
