It's genuinely amazing how silly these comments are, and yet how stubbornly people stick to an obviously ludicrous point of view. A bunch posters yelling about the good old days 30 years ago when 90% of the matches weren't watched.
It ceased to mean anything? What did the competition mean? What was the point of it?
The European Cup was founded to find out the best side in Europe, from competitors picked by L'equipe magazine, then at the invite of Real Madrid.
The point of the competition is to put the best sides in Europe against each other, and guess what, it's 2021, Barcelona are better than Ferencvárosi TC (Hungarian champions) or FC Midtylland despite being runners up in La Liga.
Having only champions in the competition makes about as much sense as only allowing one club from each City in the country to be in the Premier League, or allowing 1 tennis player from each country to play in a grand slam.
It's absolute nonsense, and it's so obviously nonsense, but out of this completely false idea that everything was better in the past people cling onto it and pretend they really want to see Leeds beat SFK Lyn 16-0 again and nothing would make them happier than seeing PSV Eindhoven beat KR of Rejkjavic 12-2 and 4-0 over 2 legs.
