So here we are. Final four time at Euro 2020. Two teams enter, one team leaves, in the Wembley Thunderdome. (OK, then another two teams enter, one of them leaves, and the two remaining teams face off on Sunday for all the marbles... I like the third Mad Max; sue me.)
There's something about one-off knockout rounds that just works. UEFA realized this last year when, due to the coronavirus pandemic, the Champions League quarterfinals were turned into single-leg affairs. That's also why they're considering scrapping two-legged semifinals and going with a final four format in one location.
