It seems to me that FIFA and UEFA are experimenting too much lately with all competitions and that their main motivation is to increase earnings and not to increase the quality of the competition.
When you include more national teams or clubs in the competition, the quality of the competition decreases, but the earnings increase due to more matches.
However, this means that key players in the main teams in the Champions League will have to play a lot more games, will be more tired and there will be more injuries.
I believe that the coaches and players of the main clubs in the Champions League are not happy with the proposed changes to the competition, but no one asks them for their opinion, what is shame.
Klopp and Pep already complained last year about the fact that their main players have to play too many games in the season, but nobody listens to them and now there will be even more games per season.
Top European coaches have complained about the policy, but it seems that complaints are just complaints without much consideration. The more matches the players will play, the greater the risk of injury to the players due to fatigue or the like. Of course that would cost the club and the players themselves, but they can't do much.
Pep Giardiola is quite vocal about complaining about the large number of match schedules in several international competitions, but there has not been much positive impact from the policies he has taken by FIFA and UEFA.
