Since it would have been quite a long post, I decided to split the CAF and UEFA seeding in two different posts.
The groups using the October ranking are based on the actual groups taking into account the zonal rank in July and October. For instance UEFA Group I had the teams ranked 1, 10, 25, 30 and 38 (Spain, France, Belarus, Georgia and Finland). Using the October rankings Group I would have been: Spain, Russia, Wales, Ukraine and Latvia.
2014 FIFA World Cup seeding: CAF (July vs. October 2011)
2014 FIFA World Cup seeding: UEFA (July vs. October 2011)
We all know FIFA brought the draw date forward to allow more time for AFC and CONCACAF qualifiers - already in full swing as I write this. I don't think it would have been feasible to postpone the draw for UEFA and CAF until now, but it was interesting (at least for me :D ) to take a look at the differences.
