I fundamentally disagree with this. Are today's players better football players, or simply better athletes? I think the latter. I actually think there was as much technical ability in previous years.. you needed to avoid (and deal with..) real, tough, harsh, late tackling and that was expected.. plus the quality of the pitches which were at times, absolutely dreadful..lol.
I think there were more 'ball' players in previous years. Now, it's all a little monotonous. The presentation (coverage) is great, far better, the product far slicker, attractive and commercially savvy'..and the hype machine is through the roof. But is the quality of football player better? I don't know about that. You think our youngsters coming through are better than those 20 years ago?
I think they're both. They're undoubtedly better athletes because that's just the way things work with modern coaching and medical improvements but to be able to create such systemic play, you need a base level that's high, very high because humans aren't naturally robotic, we're imperfect.
Every position on the pitch including the goalkeeper is now comfortable on the ball. Nearly every team passes out from the back, nearly every team plays a similar way - worse for variety of course but the nearer you get to that same style, the more 'perfect' it becomes. To be monotonous and robotic you need a consistent level and these players now are consistently great.
You might need to go back and watch old games but there were some absolute cloggers on the pitch, usually lumbering CB's or midfielders who couldn't control or pass a ball to save their lives and made up for it by kicking people instead and heading everything that moved. The long ball game was in part because of players not being comfortable on the ball. It was easier to skill your way past the opposition because they simply weren't as good.
The general standard of play now is better than it's ever been because everyone is within a smaller boundary of quality and it's raised up to the point where coaches can and do micromanage things. You simply couldn't do that with 90's players or even older than that.
The very best were still the very best but aside from the fact that they weren't homogenised into one team so much and were allowed to roam free with their quality, they were facing vastly worse players technically and physically. The best athletes shone more back then than they do now because so many others weren't that great athletically.
