The mentality is different this time. Lucho and Iniesta both said that a comeback is more complicated than it was last time and, tbh, I don't even think the players have reacted that strongly to this loss. They seemed numb. That mentality alone is a huge difference from the buildup to the comeback against PSG. Not to mention the other factors such as having only 1 week to analyze/prepare with a Clasico in the way (so really only a few days to prepare), and that's assuming Lucho even gives a fuck at this point. Then you have the fact that Juve will not choke, not like PSG did. You can't pull the same lucky shit out of your ass twice and Lucho wasted his get-out-of-jail-free card with this pathetic performance.
Actions, or lack thereof, have consequences. Lucho has shown time and time again that he will not learn from mistakes. We've practically gifted RM the league with all the stupid point dropping against small teams when we had the chance to catch up, Lucho never learned from that either.
Even if the .0001% chance becomes a reality and we go through, we'll still have to potentially face sides like Bayern/RM/Atletico in the semis and the final. Are we gonna beat Bayern 4-0 or 6-1 at the Camp Nou too? There's no way. If that game didn't outright disqualify Barcelona, it pretty much guaranteed that we're not contenders. Or we could keep insisting on these deluded fantasies and pray that somehow we end up winning against Juventus and then play BVB in the semis and Leicester in the final
. And even then, I doubt we could do it cleanly.
