塞尔希-多明格斯：进入巴萨一线队很困难，所以我选择了离开（难入巴萨一线队，塞尔希-多明格斯选择离队）

Considering response options

I think we should consider providing a quick, neutral reply. Maybe we can ask the user if they want a translation, background on the player, or insights into Barça's cantera. It aligns with the idea of suggesting only when needed. Since we don’t know specifics, we can avoid making any assertions about the team. It’s safe to mention general trends about the tough pathway at Barça due to competition and financial issues, while being concise in our options for the user, like discussing Sergi Dominguez.Formulating translation options

I think it would be helpful to offer a quick machine translation to English since that seems likely to be what the user is asking for. The original text is in simplified Chinese, and the user might appreciate further elaboration. I can provide a two-line translation and then ask if they want more context, like information about the player’s position, career trajectory, or why youth often leave Barça. I should also mention the latest transfer destination if they’re interested in it. Let's keep the options clear and concise!
