While it would make the quiz that little bit more difficult I decided to not include them because those countries can never win another trophy unless they for some reason reformed. I could maybe add those kinds of countries and give them their own section. My thinking was Euro 2020 is coming up so Europe's most successful teams will be looking to add to their existing trophies, something the USSR cannot do as they no longer exist. I'll think about adding them, maybe if more people like you comment looking for it. I may then also give them their own section to make it easier for people to guess because people don't always think of countries like that. Anyway thank you for the comment, hope you enjoyed and if you want to challenge yourself I have two more football/soccer quizzes that are more difficult than this one!
