Most, if not all, of that 1980 team wouldn't be fit enough to get into the current team. As I already said, footballers can only really be judged against those "of their time". Pele, in his prime, would probably be hard pushed to get into the current Brazil side. I'm not saying that players of yesteryear were "worse" (which is totally subjective), just that they had a "different skillset" to modern players and I doubt that football would be any different to sports that can be "measured" (e.g. athletics, weightlifting) in that modern day adherents would probably best the historical ones if it were possible to actually pit them against each other. Again, whether or not that makes it "better" or more entertaining, is totally subjective.
