How was it different.....was it played underwater or on horseback? I thought the whole idea of the sport, since its inception, was to kick the ball between the goalposts more times than the opposition. I agree with your earlier point re fitness but you state that the game is now far more advanced technically. There are certain basic skillsets in football......
1) Close control.
I see no evidence that control of the ball is any better, generally, than in previous times. I still see top players failing to keep control and using a ' heavy ' first touch. Dribbling is almost a lost art apart from rare exceptions like Messi. The art of heading has definitely declined. Players used to be able to ' hang ' in the air before heading the ball. Present football is riddled with poor heading. Use of the chest to control the ball is much less prevalent these days and crossing, generally, is woeful.
2) Shooting.
No better, no worse than its ever been. Good exponents, bad exponents.
3) Passing.
Most of the great passers of the ball...Haynes, Hoddle etc have long since hung up their boots. How many players do we talk about today as being great passers?
4) Running off the ball.
No better, no worse. Down to innate footballing intelligence.
5) Goalkeeping.
Difficult to compare. Keepers are, on average, much bigger now, which should give them an advantage. But does it make them more agile, more supple, or more quicker?
Your comments re 1966 are laughable and naive. You denigrate some of the greats of English football and state that, compared to today, its a poor standard. Did you actually watch England in the Euro's? How can you compare Moore, Charlton, Banks, Peters and Wilson with Cahill, Rooney, Sterling, Hart and Kane. These were world class players. Have you watched Brazil play in the 1970 World Cup? The single greatest and most exciting international side of all time. Watch their game with England ( played in 100 degree heat ) Watch how comfortable all the players are on the ball. Watch the first touch. See how easily they beat players. Top quality football, played by top quality footballers. A million light years away from the sort of garbage we watch England produce now at international level.
You obviously didn't watch football 30/40/50/60 years ago and your informed opinion is based on grainy black and white pictures, heresay, and an obsession with post PL football. In the pursuit of all things scientific, football is in danger of overcomplicating itself and losing sight of the basics. Players from yesteryear, with todays fitness regimes, better pitches, lighter kit and ball, would have thrived. By disregarding and disrespecting the past you are failing to understand the development of the game. Don't get seduced into thinking that no-one thought deeply about the game before 1992. From the 1920's onwards there have been brilliant and innovative tacticians all over the world.
Football, years ago, demanded more skill ,not less. A heavy, sodden leather ball. Heavy energy sapping pitches. Brutal tackling. Less protection. Yet artists still flourished...Puskas, Di Stefano, Schiaffino, Matthews, Finney, Best, Johnstone, Greaves, Baxter, Garrincha, Pele, Cruyff, Maradona and Platini. If you want to talk about technically gifted, you don't have to look any further than this.
I'm certain Mark Farringon was under water when he played for us. That aside a great post.
