PSV, Chelsea, Barcelona, Monaco and Spurs. Eidur Gujohnsen has played for some of the biggest clubs in the continent and won some of its biggest prizes too - most notably the 2009 Champions League with Barcelona.

He has never played in an international tournament, however. That's unsurprising, given that he plays for the sixth smallest country in Europe.

With a population of just 324,000, Iceland almost have no right to be anywhere close to making a major tournament. Yet that's exactly where they are ahead of a play-off tie with Croatia for a spot in the finals at Brazil. 

The tiny island nation was seeded in pot six when the draw was made in 2011 and finished second in their - admittedly not too difficult - group behind Switzerland. If they do see off the Croatian side then they will be the smallest nation to ever participate in a World Cup - something which Gudjohnsen surely couldn't have imagined in his wildest dreams. 

There are many talented players who always knew that their nation will never be good enough to give them a chance to take to football's biggest stage. Ryan Giggs, George Weah and Jari Litmanen are just a few whose national side was never good enough and Champions League winner Gudjohnsen must have surely considered himself in a similar position until this past qualifying campaign. 

Iceland lost just three times in the campaign and earned some impressive results, most notably a 4-4 draw in Switzerland this September. 

And it hasn't just been because of Gudjohnsen that Iceland have done so well. Far from it. Gudjohnsen wasn't even involved in the first half of the campaign and only returned to international action after the new year. Although he has played fairly well since returning, the striker has yet to score. However, with Gylfi Sigurðsson of Tottenham and Kolbeinn Sigþórsson of Ajax each netting four in the campaign, he hasn't needed to. 

Those younger talents, along with Gudjohnsen's experience, might just give Iceland a chance in this play-off. Croatia sacked their manager after a poor campaign which ended with defeat to Scotland in Glasgow in the last game. And it is very much Croatia that is under pressure, whereas Iceland have nothing to lose. 

This will be an interesting tie. And could lead to a fairytale ending for one of Europe's finest strikers.
