Your logic is somewhat twisted. You only listed the losses of Pep throughout his career and then compare it with a few selective good performances. EV doesnt have a huge sample size to begin with. It's as good as saying Salah is better than Messi. Without Pep, there wouldn't even be this golden foundation he has built. You'd think EV would have see something in young Xavi, Iniesta, even Pedro or Villa?
It's crazy how fans downplay Pep's past achievements where he laid the foundation for Barcelona from scratch. "Pep is a fraud, EV is a genius", honestly the most ridiculous thing I've heard. I've recognised EV's efforts at the start of the season but towards the end of the season he was clueless and was in shambles. 0-3 Roma, 4-5 Levante, I could say the same.
Keep believing mate. Actually the only positive football they played was against Juventus 3-0, where Messi played a false 9, where EV havent quite forced his rigid gameplan with little to no flexibility.
Next season is no more a transition period, so no point harping the club is in "chaos", in "turmoil", "crumbling", just because one player left. Get over it. CL KO and he's out.
