Yes, yes, yes, Barça is going to collapse because of a CL (corrupt tinpot tournament soon to be replaced by the Super League) group exit.
Also it is the end of the world that the club has its worst crisis in 20+ years and has not won any trophies for just 1 season in a row (2021-22) while numerous European top clubs can brag about 1 league title in 33 years (Liverpool), 5 seasons without any trophies won in a row, 15 years since a CL win, 10 years since a league win (Man Utd), Juventus being a joke in Europe for the past almost 30 years with no European trophies won, AC Milan with 2 scudetti wins in 20 years and 1 CL win in 20 years and the list goes on and on.
Barça on the other hand is coming of 15 years (2004-2019) of insane dominance (10 La Liga, 7 Copa del Rey, 8 Spanish Super Cups, 4 CL, 3 UEFA Super Cups and 3 FIFA Club World Cups titles), orgasmic football and legendary teams and players that will always be remembered and admired widely by football fans across the world, the GOAT winning more individual trophies than anyone else while representing the club etc.
The club is in a transitional season coming out of the worst institutional and sporting crisis in 20 + years. The GOAT leaving in August 2021 as well. Xavi a managerial novice. Laporta needing to clean the gigantic mess that Bartomeu left etc.
All in all this season is far from lost. La Liga is winnable and so is the Cops del Rey, Spanish Super Cup and likely the Europa League which I would rather win than going out in the knockout CL stages as we were very unlikely to win the CL anyway. The monetary loss from a CL group stage exit are widely overblown as already showcased in this thread by another user. This is more about prestige which is a joke anyway as we have largely been a joke In Europe in recent years anyway so this does not change anything in this regard.
Also if not for the robbery last week and tons of injuries, we would most likely have qualified. Inter are not a better team but the CL was never about the best team winning anyway. Still a possibility to qualify although a remote one.
Barça will be back winning and competing for the biggest trophies. Just a question of when and not if. Could be this season already. Laporta has already done a tremendous job changing the squad for the better just within 1 year. The squad is young with tons of highly rated young players and talents with many more coming through.
New stadium coming within a few years, most deadwood gone next summer, wage bill under control, still a massive pull as a club etc. There are many reasons to be positive.
