I don't think this is a very accurate assessment of how football has developed over the past fifteen years, especially over the past five. The best teams in the world press a lot less now than they did in the back end of the 2010s, and the game has slowed considerably (Manchester City a key eg). To add to that, while pressing has become more intense since 2010, the game is much more compact, especially in England. End to end football is extremely rare nowadays, it tends to be teams camped in one end then the other depending the momentum in that moment. You don't get basketball style matches (the Euros, especially, was very very controlled). So I don't really buy the "footballers are much fitter" story – compared to the 90s, sure, but premier league players were actual drunks. Compared to early 2010s it's not been a major shift, even if the form of that fitness has differed. Leeds and Atalanta were probably the most obviously doping teams, the entire Liverpool team had masses of TUEs, too.
Also unconvinced by this. Cycling over the past decades has led the way on every new PED development there is. Plus, footballers aren't performing at totally abnormal levels of physical function in the way Pogacar is here. Someone like McTominay, one of the fittest players in the Premier League, ran a 16 minute interval 5k, which is not that out there (probably translates to an 18 minute non-interval 5k, and I have friends/family who run that). Pogacar/Vingegaard's performances are so far beyond what footballers do. I can't speak for other sports, I know them less, but I don't see much evidence in terms of athletic performance that cycling is catching up to a sport like football, given that most footballers are well within the realm of low-level doping rather than 60% HC doping.
