Explaining new challenges in soccer

I can explain the new challenge system in soccer, how it differs from VAR, and its potential pros and cons. It's still pending approval by IFAB, with a timeline suggesting a trial in events like the Coppa Italia or Primavera. Reports state that each team may receive two challenges, with a third if the initial ones succeed, focusing on subjective incidents. I should ask the user if they prefer a summary, source link, or deeper analysis while keeping my response concise.Summarizing coach challenges in Serie A

I'm crafting a concise response in Chinese about Serie A considering "Video Support" (VS), which adds a coach's challenge system to VAR. Each team’s coach may have two challenges per match for suspected missed calls, though the headline suggests these might not be regained after use. I’ll highlight uncertainties, explain the possible challenge types, and motivations—like reducing missed calls and alleviating referee pressure. It still needs IFAB approval, potentially for trials in the 2025-26 season. Should I track official confirmations or existing experiences with such challenges?
