The whole Spain going to playoffs thing is a bit overblown I feel.
None of the teams in playoff contention I feel would be tough for Spain to overcome.
Plus a European team in South America for a world cup is about as worthless as a Zimbabwean Dollar. (I know this is an worthless point nowadays as travel is easier than its ever been and 'away' matches really aren't as taxing as they once were, but it's still a decent point, even if its slightly irrelevant) thus making Spain not much of a force.
I sorta hope Argentina win though
