Geographically. If you read what I said, I didn't mention quality of the teams involved. I couldn't care less if some 'better' (according to the notoriously suspect FIFA rankings, which I've only encountered when used by people trying to back up fatuous arguments like this) European teams miss out at the expense of Egypt, Iraq etc. I'd find it much more interesting to have a genuine spread of nations from across the world.
... and surely when FIFA seed tournaments such as World Cup qualification?
You may not like them, but they are self-consistent and transparent.
Incidentally, do you really think FIFA have appropriated qualification spots according to ranking? Have a think about the 2006 FIFA-Adidas-Budweiser-Avaya-Coca-Cola-Continental-Deutsche Telekom-Emirates-Fujifilm-Gillette-Hyundai-MasterCard-McDonald's-Philips-Toshiba-Yahoo World Cup in Germany. Laboured point maybe, but do you see what I'm driving at?
I'm not 100 % sure. On the one hand, yes, they should have a spread of different regions and on the other, they should keep one eye on which confederations do actually contain the better teams. You said "I'd much rather see a redressing of the imbalance in qualification places, giving more spots to Africa and Asia " - I raised the question as to where the imbalance was. According to the only realistic attempt to quantify things, the balance is strongly against Europe in favour of Asia.
I guess the question is what you want from a world cup - something inclusive (which, yes, does have its merits) or the best countries in the world fighting it out?
