This is worrisome - I can't use a lot of the good players on my roster for the Supercup because of the National team tournaments. I assume they should be done before the Supercup and I will eventually be able to update my roster; if not, it will be a much more difficult match (though the Terriers FC also have at least one player currently competing).
Looks like I only have one player who might not be available for Supercup. It shouldn't matter what 11 the Polar Bears put out, I don't have much of a chance. Other than 500 experience, what do you get for winning the Supercup?
