UEFA are to consider bids from Italy, France, Turkey and a joint bid from Norway/Sweden to host the European championships in 2016. As far as I can see Turkey have to be considered outsiders. I dont know anything about the state of the stadia in Turkey. I assume that the likes of Galatasary and Fenerbache have decent stadia as they have hosted Champions League matches, and sure Istanbul has hosted the Champions League final (Go on the ‘Pool. Won it 5 times, beat that Man Utd) in the Ataturk stadium, which has a capacity of over 80,000.
Also, I think Uefa will also rule out the joint bid from Norway/Sweden as this gives up an additional finals place to the second host nation, and after the debacle with Poland/Ukraine I would hazard a gues that they are not looking favourably on future joint bids.
So that just leaves Italy and France, and with a Frenchman as the President of UEFA, your guess is as good as mine as to where the finals will go in 2016!
