阿尔瓦雷斯：我小时候曾去过皇马试训几天（阿尔瓦雷斯回忆：童年曾赴皇马试训数日）

Responding to user inquiry

The user provided a Chinese sentence: "阿尔瓦雷斯：我小时候曾去过皇马试训几天." They might want a translation or some context. It's probable they're looking for clarification on who Alvarez is — likely Julián Álvarez from Man City, who mentioned training at Real Madrid as a child. I think I should respond in Chinese, providing a concise translation: "Alvarez: When I was a child I went to Real Madrid for a trial for a few days." I could also ask if they'd like more information or the source.Clarifying user request

The system offers planning tools, but for this request, a plan isn’t necessary. I should avoid making assumptions. The user's phrase notes an experience related to a short training period in Madrid, which is good to clarify. I think I could phrase a response that includes a paraphrase in Chinese and English: "This usually refers to Julián Álvarez." However, to be safe, I can mention there might be other Alvarez. I’ll keep it concise and ask how they’d like to proceed: do they need the source, full text, more background, or the English version?
