This loss has sparked criticism against Chivu, who is relatively new to the role. Sacchi believes that the backlash is understandable, given the team's performance.

"It's inevitable that there would be criticism when a team loses at home to a lower-ranked opponent," Sacchi said. "Chivu's team is still finding its footing, and it's unclear if they are truly his team or still following the style of their previous coach, Simone Inzaghi."

Sacchi suggests that Chivu needs to focus on building a strong relationship with his players and convincing them to follow his vision. He believes that harmony and balance are essential for a great team.

"On Sunday, I saw a team that was neither harmonious nor balanced," Sacchi said. "Harmony and balance are the foundation of any great team."

When asked about Napoli, Sacchi praised their approach to building a team. He believes that they have a deep squad that can compete in both the league and the Champions League.

However, Sacchi also warned that international matches can be draining, both physically and mentally.
