Got it, let's tackle this article for "Liste U20 France Rugby". First, I need to structure it naturally, right? Start with an intro that sets the context of the U20 French rugby team being a hot topic, especially after their recent 2025 Six Nations win and World Rugby U20 Championship run. First, the main heading should be h2? Wait no, first the title? Wait no, the user said natural headings, so first h2? Wait no, let's start with an intro paragraph that hooks, mentions the keyword right off the bat. Wait, the keyword is Liste U20 France Rugby, so the article should be about the squad list, their recent performances, context around the team. Wait first, h2: Pourquoi la liste U20 France Rugby attire-t-elle autant l'attention en 2025 ? That makes sense, because 2025 is when they won the Six Nations, right? The context says they won 2025 Six Nations, beat Scotland, finished second in the World Championship? Wait no, the context says they qualified for the final by beating New Zealand, right? Oh right, the context mentions they beat NZ to get to the final, won 2025 Six Nations, beat Wales 67-17, had a good game in bad weather against someone?
