Didn't united get to a final without winning a game in the group stages? In the old EC every game was do or die. It evens out IMO about which one is harder to win.
No, because teams with 6 points rarely, if ever, get through the group stages.
In 98/99 they won two and drew four, in a group containing both Bayern Munich and Barcelona, and finished second by a point, going through to the knockouts as one of the best placed runners up.
In 07/08 they won five and drew one, topping the group.
In 08/09 they won two and drew four, topping the group.
In 10/11 they won four and drew two.
The lowest points total a team has progressed through a group stage with since they adopted 3 points for a win in 1995/96 was 6. The first time it happened was in 2013/14 when Zenit finished 2nd with 6 points, and the teams in 3rd and 4th both had 5 points, the second in 2015/16 when Roma finished 2nd with 6 points, the team in 3rd also had 6, and the team in 4th 5 points. Both teams won 1 and drew 3, and neither progressed to the final. Never has a team progressed through a group stage without winning a game.
In fact, it'd be far easier to reach the final of a two-legged knockout competition without winning a game. You could go through on away goals every round, or on penalties if you limit it to normal time/extra-time. Seems even more likely to happen when you're only playing 3 rounds before the final.
As I see it, your win in 05 was a better achievement than any of your others precisely because you played more games, and against better opposition. By the same token, both 99 and 08 were more impressive for United than 68.
I really don't see what's so controversial about saying that the Champions League is a harder competition to win than the European Cup was, yet the European Cup was a harder competition to qualify for than the Champions League is.
Is there a greater yawn-fest than the anti-historiography that takes place to undermine Liverpool's past?
It's not undermining your past. You dominated domestically and did very well in the European competitions you were in through the 70s and early 80s. You were one of Europe's best teams during that period, particularly from around 75 to 85, just like United were one of Europe's best from about 06 to 11.
I find it incredibly odd that Liverpool fans simply can't accept that playing just three or four rounds to reach a final, one or two of which would be against literal minnows, is easier than playing a dozen or more games against Europe's top sides.
This discussion began because it was claimed that a) the European Cup was at least as difficult to win as the Champions League, and b) Liverpool's European haul would not have changed had the Champions League format been in place during your heyday.
Just so it's clear, Liverpool winning 4 European Cups when they did remains very impressive. Liverpool, or any team for that matter, winning 4 Champions Leagues, including back to back titles, in the same time period now, would be more impressive.
No one creams themselves over Real Madrid winning the first five other than Real Madrid fans. This isn't really any different.
