I personally think that the Europa League should be the only tournament together with the Champions League. The appointment of the Conference League should not have taken place, but I also understand that it is a commercial thing. All a lot of turnover for the football association, and in this way very small teams also get the chance to participate in a European round. But the difference in the prize money between all 3 tournaments is of course bizarrely high.
Now the rules are good enough with the many tournaments that are presented so that small teams with seemingly ordinary strengths can get motivation to develop because they have seen the opportunity to play in better tournaments. So it would have been better if the Europa League and Champions League were separated because now there are a lot of great teams in both tournaments so that makes the increase in attendance even better in both.
