Come off it. It's complete nonsense to say that it wasn't easier to win back then. The trade-off, of course, was that it was more difficult to qualify for, at least from a competitive league, because you either had to win your league or win the European Cup. Nowadays, as we know, you can finish 4th and get in.
I don't know how you can say with that degree of certainty that Liverpool would have enjoyed the same European success when the competition is so much more difficult to win in its current format.
The thing about barely being able to lose back then is utter nonsense too. The old format basically had a tie against a really, really shite team in place of the group stage (you even had a fecking bye through that one year), so if you lost that then you weren't winning the thing anyway. Get through that and you're in the last 16, except it's a far weaker bracket than you see today.
There'd be plenty more pitfalls for Liverpool if the current format was in place back then, including their domestic rivals, and the title challengers from the other top nations.
I swear the only reason you guys try so hard to make it seem like the European Cup was difficult to win is because you're actually seething that United have more in the current format.
