8. Euro 2020 (2021):
Most countries in Europe closed their borders in 2020 because of the global health crisis. The free movement of people wasn’t such a good thing when there was a genuine risk to millions of lives. Meanwhile, UEFA planned to host a tournament in 14 countries across the continent. This seemed like a crazy move because it meant thousands of people traveled to games.

Immediately, Ireland and Spain withdrew two stadiums from the tournament. But it went ahead everywhere else. Players tested positive over the course of the next two months. Furthermore, there were spikes in cases across the U.K and other nations where fans gathered in their thousands. In terms of entertainment, it was brilliant. However, when it comes to public health, it was very controversial.
