Then why are they 12's for Euro 16? Why can they be backed at 14's for this World Cup?
Well firstly, I agree with the above assessment that they are an appalling price for this World Cup. But that's just my opinion of course. Reasons why they are 12/1 for Euro 2016:
1) It's in France, on their doorstep.
2) The Euros have been increased to 24 teams remember so it's fairly hard not to qualify. Belgium's group contains Bosnia, Israel, Wales, Cyprus and Andorra. Top two qualify, best third-place qualifies, and all the other third-placed teams get one final crack at a playoff.
Belgium are probably rated as high as Belgium could ever be rated right now, so with a World Cup four years away it's very hard to know how they'll be performing by then. Plus qualification will be tougher, and there will be the likes of Brazil and Argentina to beat as well.
who would have thought that Uruguay would reach the semis in 2010, or Turkey in 2002 ?
That's where the luck of the draw comes into it. Uruguay beat South Korea and Ghana to reach the semis. Turkey beat Japan and Senegal. It's all very well doing these predictor thingies and working out a team's path to the final but in reality it just takes one unexpected group winner or runner-up to turn an awful draw into a plum draw.
