Kids born in 2000 and beyond, that never got to watch the PL in 2004, are commenting on things they didn't even witness first hand.
You see these comments quite often, criticising that era as been poor quality, as if 2004 is comparable to the 1960's.
Just because it is 20 years since then, doesn't mean football has advanced much, the difference between the 70's to 90's is stark, but the difference between 2000's to now, not so much.
If anything, outside of Messi and Ronaldo, the early 2000's football was actually better.
All that has changed now is more advancements in statistics, high pressing tactics and tiki taka passing tactics.
If anything, the birth of strict Guardiola style tactics has actually decreased the quality of the individual. Players nowadays lack flair, creativity and moments of magic compared to the early 2000's.
It is a mistake that is made a lot, where people think everything improves as time passes.
You see the same thing with kids of to0day criticising 1980 - 2000 Basketball as being worse, when it was infact better.
It is also same with Mr Olympia, kids think it is better now because of recency bias. Dorian Yates from 1992 to 1997 walks through the entire Olympia competition if today. Lee Haney was Mr Olympia champion from 1984 - 1991. Thats between 40 and 33 years ago, and he would annihilate the competition of today.
