Wow, I didn’t know that the introduction of the Swiss system and the change in the Champions League format would also be accompanied by a change in the limit on the number of participating teams from one country. Previously, it also happened that 5 teams from one country participated (if a team outside the top 4 won the Champions League or Europa League), but now this will happen every year, plus if in the future a team outside the top 5 wins the Champions League or Europa League, then 6 at once teams from one country will participate.
