Bayern's achievement is already more impressive, but you know, people like simple numbers and not "an indicator averaged on some parameter."
As for Barcelona, I don't want to upset you, but their success in La Liga is entirely due to the fact that Real Madrid sucks. It's effectively winning the league without a rival. As you can see, there's been no progress in the Champions League, the defeat to Inter has been followed by a defeat to Atlético. La Liga is essentially stagnating (Atletico Madrid sucks too), it's nice to be champions in any case, but I'd like to see some overall progress.
No you can never upset me, I know that there are just two teams plus sometimes Atletico who battle in La Liga, but at the same time you have to admit that we are really showing Spain that Academy is sustainable and investment and trust in youth is playable even against Galacticos.
You want to remove PSG and ask a team of average 24 years old to win in French league? Or remove Inter and Napoli and Milan and ask the same to win Serie A?
Champions League is always a problem and that is hopefully what the youngsters will keep gaining experience in. So don't worry nobody is upset at such criticisms since everyone in Barca says Champions League is next.
But at the same time, seeing how close we were to facing a bleak future a few seasons ago, with stars getting cut and our stadium rotting, today we have a team that should not yet be at their maximum power, and are back at our beautiful Nou and provided the most watchable team in Champions League for 2 seasons (PSG only shows up second half lol). We shouldn't feel like it was a failure at the same time.
