Jumping in a few days late on the Xavi stuff, I agree that he was inadequate at times as a manager but I think he was really hurt by the roster construction. Last season, the team looked much better with a true CDM and I would say the best setup he had was Dembele at RW taking guys off the dribble with Pedri or Gavi at LW with those two and FDJ rotating around frequently. The ball moved well, solid chances were created and the defense looked sturdy. I am not sure what's Xavi's ultimate vision was of the team this season, but the LW position never looked good until Raphinha started excelling there later in the season, and the midfield defense was kind of awful. Without a forward that could consistently open up defenses, I think Xavi had hoped that fast ball movement and guys like Gavi, Pedri, Frenkie, Gundogan, Lewa, Fermin, Cancelo, etc moving around in the middle of the field would create openings, but the attack always looked a little out of sorts. I think the attacking numbers at the end of the season were solid overall in terms of stuff like chances created and expected goals, but it felt like in most matches the team would go through long lulls of ineffective ball movement followed by 10 minutes where they would score multiple goals. The team really needed a veteran wing that could create off the dribble and a CDM that could help with the press and protecting passing lanes in the center of the pitch, which in turn would help with the attack if possession could be won back in the opponent's half. Ultimately, I think Xavi prioritized playing safe and covering up Barca's weaknesses versus aggressively going at other team's weaknesses. Was that a philosophy thing? Personnel issue? Could he just not properly find the weaknesses in the opponent and implement a plan to exploit them? I really don't know, but after 2.5 seasons I am inclined to believe the latter option because it always felt like the team was set up to not fail rather than go for knockout blows.
As for Flick, I guess I'm interested to see a new take on this team, but it's hard to get excited about a guy with his history. He has 1 1/2 years of coaching a top club, including one year where he won 6 trophies. However, that year was the season that covid ruined, and he has virtually no success outside of that season. His Germany team looked awful, and he hasn't worked since he was fired from there. I'm trying to convince myself to just focus on the one great year on his resume, but this sure looks like a guy that's going to be fired within the next year. It's giving me Tata Martino vibes where the team basically said let's just bring in an outsider to shake things up, and everything he did fell flat.
