The goal of this challenge is to spend at least one season in each country listed in claassen’s megapack. That’s it. Any other rules are up to you. Simple,isn’t it?
Just a heads-up though: Resign immediately when you have completed at least one season in that country as the disparity between countries can go as high as between Tahiti and Armenia. Also, try to get the highest coaching badges as fast as possible so that you can go to your next job quicker.
