MICHAEL Duff believes qualification for Euro 2008 is all to play for as he prepares for Northern Ireland's crucial clash with Iceland tonight.

It was feared a shock defeat against Latvia on Saturday would have left Nigel Worthington's men with a mountain to climb in order to finish in the top two of Group F.

But with closest rivals Spain and leaders Sweden failing to record wins at the weekend, and both having games against Northern Ireland to come, Burnley defender Duff believes their fate lies very much in their own hands.

While a showdown with team-mate Joey Gudjonsson has been avoided due to the midfielder picking up his second booking in Iceland's 1-1 draw against Spain at the weekend, Duff is adamant the squad is determined to make amends for the weekend's shock outcome in Riga, not least because a win would put them top of the group.

"I think we did let ourselves down but it shows how far we have come recently that people expected us to turn up and win there," said Duff, ahead of tonight's showdown at the Laugardalsvollur Stadium, Reykjavik.

"There are no easy games in international football - that may sound a cliche - but we didn't perform and we didn't get the result we wanted.

"Hopefully we've got it out of our system and we can turn things around and get a positive result tonight."

And Duff insisted that rumours of friction within the Northern Ireland camp were wide of the mark.

There was said to be unrest that players were not allowed out of the team hotel, as well as disputes over team selection and training methods, but Duff said: "I don't think there's been friction, there's been talking about the performance.

"We all know where we want to go and where we went wrong - I wouldn't say there's friction in the camp though.

"It's about staying together and being positive. I don't think anyone could argue about things because the fact is we didn't play very well.

"The lads know that, they are honest enough to admit that we need to do better if we want to do well.

"It shows how far we have come - 12 months ago we got beaten 3-0 in Iceland and everyone thought 'here we go again'.

"But we turned it around with good performances by sticking together which we have done and obviously we can bounce back."
