Brazil and China have already claimed 2 of the spots.
The last 2 are between, providing we win against Argentina,- us, Nigeria, Cameroon, New Zealand,Chile, Thailand
Nigeria none left to play, on 3 points, -2 GD
Us - 0 points -2 GD
Cameron & New Zealand 0 points both on -3 (last game is vs each other)
Chile & Thailand both 0 points, -5 & -17 GD (play each other last game)
So. We can safely count of Thailand. One of Cameroon and New Zealand will miss out so as long as one doesnt win by a huge difference. Its not much but we are 1 goal difference better off than both of them.
We are 2 goals better off than Chile, but that might not count for much seeing as they're going to be playing Thailand.
So by my reckoning, provided we of course beat Argentina, I think we have a great chance of going through and I think it'll be along with Chile making up the last two 3rd place spots.
