Sometimes not all managers and teams click, that doesn't mean that the team was terrible, but it also doesn't mean that the manager was bad. That is a risk that the managers are taking, Garcia wasn't the manager to lead Napoli, that doesn't mean Garcia is a bad manager, the downside is that he will be labeled as the guy who took over a champions Napoli team and "ruined" them, not like they were doing that terrible to be fair, they are doing fine.
I think that's going to be the label for him and he will have harder time finding a job, or at least at a high level club. This is going to be fine though, because if he finds a club he clicks well with, then he is going to do better and he will show himself to be a good manager again.
Previously, Garcia also lost his job at Al Nassr. Fans said Al Nassr's dismissal of him was entirely Ronaldo's fault. But I wonder if he has talent as a coach.
Obviously, with the Italian champions' quality players like Khvicha Kvaratskhelia and Victor Osimhen, Garcia's achievements cannot satisfy the team's leadership and fans. It's Garcia's fault, and it's just his fault. The team's condition is seriously declining, and there are many rumors about Osimhen's departure. If Osimhen leaves, what will happen to the team? New coach Mazzarri needs to come in and stabilize the dressing room and restore the spirit of the entire team. Because here he faces a challenging start while Napoli's matches after the international break are against Atalanta, Real Madrid, Inter and Juventus.
