Sandro Rosell and Josep Marie Bartomeu sold their soul.
Rosell forced out Pep, did the illegal Neymar signing. Bartomeu sold Neymar and bought Dembele, Greizmann, Coutinho et al. Both hired and fired numerous managers and basically ended the La Masia talent pipeline. Furthermore both are criminals.
When Pep left they had one of the greatest collections of talent ever assembled playing Cruyff’s brand of football and those two fucked it. I don’t know how a team with Messi, Xavi, Iniesta, Neymar, Busquets, Pique and Jordi Alba at its core managed to win only one UCL and 8 years later staring down the barrel of a bankruptcy. I suppose it is a cautionary tale.
