With the UEFA EURO 2008 party now in full swing, FIFA.com wants to know which team you think will prove the biggest surprise package. Germany, Spain, Portugal, Italy, France and Netherlands are among the favourites for most football fans, but which underdog do you see causing a stir at the tournament?

With Greece's shock triumph four years ago in Portugal still fresh in the mind, the confidence of some of the so-called lesser sides should be sky-high up among the Alps. The Greeks, themselves, will be hoping lightning can strike twice, while co-hosts Switzerland and Austria - tipped by seemingly all pundits to slink quietly out in the group stages - could well be primed to take advantage of home comforts and cause an upset or two.

Croatia, conquerors of England in the qualifying rounds, will be aiming high and Guus Hiddink's Russia, with a handful of players from UEFA Cup winners Zenit St. Petersburg, could be a side to watch. Poland, Romania, Czech Republic, Sweden and Turkey also represent decent outside bets in what looks an astoundingly balanced European finals.
