As i've said before, nobody, NOBODY in this current disasterous period with awful management and coaching should be evaluated at face value. Every single player that looked great some years ago has deteriorated. Every single player that looked good at other clubs, when we acquired them, looks deteriorated. No exception. Only another up and coming guys like Yamal and Cubarsi, who are little kids yet and haven't eaten the poison enough, look outstanding despite their age. That should get you a clue. Complete revamping is needed. There's no way this squad should play worse football than Girona, let alone likes of Granada and Villareal. Stop with the emotional hysteria.
I don't believe current Barca squad is among top5 in the world like some people here have suggested, only because it's incredibly unbalanced in various ways. Lots of players with wrong profile/age/style/mentality have been acquired. Lots of very young kids have been played to death or used in wrong ways. Lot's of positions have not been served proper acquisitions at all. That's also on the disasterous incompetent management. But even with these makeshift squads we should do better. Much better than under the last years under Xavi and before too.
And then add up the woodoo doll injury contamination that has been problem for years under the similar staff, both training and physio. There's no way that's just unfortunate accident. Both shitty training routines and bad assessments from therapists have made the avalanche rolling.
tl;dr: everything is shit, Kali Yuga for FC Barca
