For anyone interested, came across a great tool to check all the possible permutations for who will qualify from each group, based on their remaining games. For example for Argentina’s group C:
-If Argentina and Poland tie 0-0, then both go through, unless Mexico beats KSA 4-1 or more. But if they tie (by any score) and KSA beats Mexico (by any score) then Poland and KSA qualify respectively.
-If Argentina and Poland tie 0-0, then both go through, unless Mexico beats KSA 4-1 or more. But if they tie (by any score) and KSA beats Mexico (by any score) then Poland and KSA qualify respectively.
