that's quite reasonable. let's just say the match between Inter and Barca against Muchen is a defeat for both. but both will win against Plzen, which means there will be no change in the standings. which would indicate that Barca will not qualify.
to qualify, Barca must fight hard. as well as hope that Plzen will beat Inter. even with a draw, Inter has a better chance of qualifying.
This is even certain to happen because indeed with things like what we see now with Barcelona's current points acquisition and facing Bayern even though it's playing at Camp Nou it still doesn't change anything and doesn't change that Bayern are still very strong.
I think it will be the end again and they will have to settle for the Europa League for the second time.
Unfortunately, their squad looks convincing but a few mistakes and some internal problems with injured players changed everything for Barcelona.
