德国U21主帅：不担心失去卡尔，他去成年国家队我就完成任务（德国U21主帅：不担心卡尔升入成年队，那意味着我已完成使命）

Considering user options

The user seems to have pasted a headline, and they might want me to rephrase or translate it into English. The headline translates to: "Germany U21 coach: Not worried about losing Karl; if he goes to the senior national team, my job is done." Since it’s a bit ambiguous, I think it’s best to ask a clarifying question. I’m considering offering options like translation, a 200-300 word news expansion, or background information on Karl and the coach. I'll respond quickly and concisely in Chinese.
