As you said, 2020 may the worst year for all sport activities becuase of limitations, fear and some strict rules.
But here in my country 2021 was also not good. Challenges with out fans was not cool and also not excited.
And yes. I think big clubs lose more power. I don't know what will happen this or next seasons. But last 2 years took some good reputations. Yes maybe some big clubs won the title but. But you really think we watch same teams as we did before covid? No I think. Big clubs may won the title but some small teams gained a good things I think. And we will see really what's going on.
It's critical since 2020 up to this moment for some leagues and countries. But as much as I see, there have been recovery plans for these sporting events and as well as clubs or sports organizations on how they're going to keep up with the current situation.
So far, we've been seeing good progress in the sports area and closed indoor audiences have been there as long as the medical protocols have been maintained and implemented.
