天空：曼联1月不会积极出售齐尔克泽，最近他发挥了一些作用（天空体育：曼联今冬不主动出售齐尔克泽，近期表现已有所贡献）

I'm considering that the user might be looking for an article or details from a report. I want to check the network status and sandbox modes, noting that the developer's description doesn't clarify all settings. Assuming defaults, we can focus on answering contextually and ask what specific information they want: a translation, summary, or analysis? I'll provide context about United's position regarding sales and Zirkzee's performance, being careful not to speculate too much on specific details.I need to make sure I'm not inventing stats and can offer general insights while also being ready to fetch more details if the user wants. I can respond with a concise summary and ask if they need the full story or source. It's worth noting that Martial left in summer 2024, and I can mention United's striker options. Even though the user is likely Chinese and may not need a translation, I’ll respond briefly in Chinese, acknowledging the report and asking if they want a link, summary, or analysis. Keeping it all succinct is key!
