Exploring coaching changes

I could explain "量变到质变" in terms of data thresholds like sequences of passes, recoveries in the final third, and pressing triggers. However, I need to be cautious since my knowledge cutoff is in October 2024, and it’s now December 27, 2025. So I can't claim to have the latest information. I can discuss known facts up to 2024, like Cagliari's survival and the coaching changes with Ranieri and Nicola, though I'm working through some uncertainties there.Considering tactical improvements

I’m exploring the possibility that Cagliari appointed Fabio Liverani in the 22-23 season and then Ranieri later. For the 24-25 season, maybe they appointed Vincenzo Vivarini, but I’m not entirely sure about that. To be safe, I should avoid specifics beyond 2024 and clarify what the user wants. Since they used Chinese, I’ll respond in that language with a concise, helpful answer.

I can present a technical breakdown on how small improvements—like pressing height, compactness, and set-piece routines—can lead to bigger qualitative changes, using metrics to monitor these improvements without making up numbers. That sounds like a good plan!Proposing analysis framework

I can suggest a step-by-step "技术靠谱" analysis framework, focusing on a video and data triad that includes defensive and offensive phases, transitions, set-pieces, and squad usage. I want to provide testable hypotheses and show how to verify them using public data, like StatsBomb and Opta from FBref or Understat, and also offer sample thresholds.

For player roles, I can mention that Cagliari had players like Gianluca Lapadula and Zito Luvumbo. To keep it generic and avoid confusion, I can refer to concepts like "边翼位/边后卫向内收缩" or "双前锋" instead of getting too specific with names.Summarizing soccer transformations

The user might be a soccer fan, so I could reply with concise bullet points summarizing the transformation and ask if they’d like a deeper dive with data or a match example.

• 定义“量变”：stats like pressure counts, PPDA, recovery time, forward entries, set-piece xG, and off-the-ball retreat speed; “质变”：positive xG difference, fewer goals from set-pieces/counter-attacks, field advantage.

• Tactical adjustments include ball progression strategies, defensive formations, counter-attack principles, set-piece strategies, and player consistency.

• For verification: listing specific indicators and target directional changes without specific numbers.

• Training methods can involve several drills focusing on pressing and recovery.

Finally, I’ll ask if they want a review based on specific matches or public data comparisons, in Chinese for clarity!
