Is there not a scenario where we could beat Croatia, be on 4 points, and still not make it through? Everyone seems to be certain that 4 points will definitely get us through. But if we win 1-0, we'd be on 4 points and -1 goal difference. Then...
A If Switzerland beat Turkey 3-0, they'd be in 3rd place with 4 points and 0 goal difference.
B If Finland draw with Belgium, and Russia beat Denmark, Finland would be in 3rd place with 4 points and a 0 goal difference.
C If Ukraine and Austria draw (very likely), Austria would be in 3rd place with 4 points and a 0 goal difference.
See where I'm going with this? Please someone tell me I'm wrong.
