The thing is that it's very hard to compare players from different eras. The players are so much better trained and the sport is so much more competitve in todays football compared to 50+ years ago. Here's the results from the Brazilian WC-winning 1970 team taking a "Cooper test" (run as far as you can on a flat track in 12 minutes) of their players:

Which would be good for a 40+ year old running a couple of times a week today, but would be absolutely shocking for a professional athlete.
Even in the mid 80's Maradona got away with being in horrible physical shape (he ran 2550m in a cooper test in 1986), which there is no chance he'd get away with today.
It's a totally different sport nowadays. The players are faster, stronger, better tactically and has better stamina than they did in earlier eras and the tempo of the game is so much higher.
Hence why comparing players from different eras is a bit meaningless. Todays footballers are objectively much better than the players of the past, but maybe not compared to the competition the players from the past faced in their time. Football has developed a lot the last couple of generations. That 1970 Brazil team would probably get hammered by Burnley anno 2023.
