Why should they have done? The pots were geographical, they had nothing to do with the strengths of the teams.
The rules were changed so that one of the Euro teams would get drawn into pot 2, which would result in that team getting a tough group. The chances of this happening were of course 1/9 for all the euro teams.
What should have happened, and what happened the last time this situation occurred back in 2006, is that the lowest ranking Euro team automatically gets put in pot 2.
But of course, who was the lowest ranking Euro team this time round? Yes that's right, France.
So the rules were changed.
FIFA is so bent it's unreal!
