What a lot also forget, is that there was 1 sub back then, and we probably had a squad of 15 for potentially a lot more league and cup games than now, and it was damned sight harder than it is now, some of these fairies wouldn't have last 5 minutes back then. A team back then were a mix of brawn and skill, and we had the best. For nearly a decade this squad were one of the best in the country, sadly they never showed it in the one european competition that really mattered, the European Cup, it should have, but even then typical city reared its head occasionally. Don't get me wrong the cup winners cup win was a great achievement, but it just didn't contain the best in europe, and City went and got knocked out of the main one by a relative minnow.
I don't think that its really a fair question to compare now and then, its completely a different game now, built around different things entirely, a number of those players weren't athletes, but they didn't need to be, they used their ball skills.
For instance Richards wouldn't have made their reserve team, of the current squad that would have made their squad, Bellamy, Tevez, Zabaleta, Vieira, Ireland, and maybe Given, but I don't think he would have been first choice.
