The major cause of Barcelona drop last season isn't stillclear to me though or let's just say they truly had a bad season just like you mentioned and remembered that the season Xavi joined the club they won the laliga but the following season which was last season I think turned out to be different. I don't know if same is going to repeat itself but I doubt it actually because I know Flick is more experienced and I could recall that the financial situation of Barca wasn't in a bad shape while Xavi took over but it's was in a critical state when Flick took over and still maintained it well, I guess that should explain alot...
Xavi Hernandez did pretty well in his first season as manager of Barcelona, but do you know what? They saw players leaving and he wasn't backed up properly due to financial woes within the club. Faulting him wouldn't be a great idea in my opinion, maybe if he was backed up with finance, he wouldn't have faced some setbacks. Atletico Madrid shared points with Real Sociedad away from home, it was a great assist from Griezmann to Julian Alvarez to put Atletico Madrid ahead during the game. That equalizer from Sucic yesterday was damn beautiful. Oblack made great saves to resit Real Sociedad but that goal was unsave able.
