I have several issues on my mind that have preoccupied me. I'll summarize them, and perhaps you can help me refine my thoughts.
1. I have watched Barcelona's documentary from the past season, and there were times when the team was going through a mental crisis. However, they immediately overcame it with unity and the belief they had in Xavi and themselves. They managed to emerge from that crisis and ultimately won the league and the Supercup. After watching the documentary, I came to believe that even if Xavi doesn't have any specific strengths, at least he is one of those coaches to whom players remain committed. Now, I'm in a situation where I think if this sole strength of Xavi also collapses, what else will he have for survival?
2. We can consider examples of teams that changed their coach mid-season, and everything went worse. Conversely, we can think of examples where teams changed their coach mid-season, and everything turned around. Therefore, I don't believe we should persist with Xavi at any cost until the end of the season. Defeat has significant dimensions and widespread consequences that, if accumulated, can lead us into irreparable crises.
3. Given the logic in the second part, we conclude that if there is a decision to change the coach mid-season, we cannot opt for someone at the same level or even lower than Xavi. Marquez represents such a choice for me, even more uncertain than choosing Xavi at this time, especially with the likelihood of a worse outcome than Setien. In fact, it's a gamble with a higher probability of loss than gain.
4. De Zerbi is probably fascinating for all of us. We know that. However, in recent years in Europe, there have also been figures like Nagelsmann and Ten Hag who faced defeat on a bigger stage. There is no certainty that De Zerbi will be like them, but let's let another team take that risk, a team that is in a better position than us. We are in crisis and in transition. The most prudent decisions for us are low-risk and secure choices, even if they come at the cost of less excitement.
