Evaluating news implications

I want to acknowledge the news about UEFA Champions League registration rules and their deadlines for knockout rounds. It’s important to explain the rules without asserting new facts. Notably, a potential return could impact competition for goalkeeping roles, especially with Iñaki Peña at Barcelona. He has been Barça's first-choice keeper when Ter Stegen was injured, and having him back would strengthen both defense and buildup. I can ask what further information the user might need, like a translation or injury details.Formulating a concise reply

I need to translate my response into English. If confirmed, this suggests he’s nearing full fitness, and he could be named in the UEFA Champions League squad, likely displacing the backup keeper. The timing of this depends on getting a medical green light. I can ask if the user wants a quick preview on how his return could affect Barcelona's play, or if they need info on UCL registration rules. Since I can't fetch sources directly, I can suggest checking official channels.

大意：据马卡报道，特尔施特根已参加巴萨今天的合练，他有望伤愈复出，并进入欧冠大名单。

可能影响：

• 若获医疗放行，他将重回首发门将位置，提升后场出球和高位压迫下的稳定性
• 这意味着替补门将的出场时间将减少
• 欧冠名单需在淘汰赛阶段按欧足联注册窗口提交，是否入选取决于最终体检与教练组决定

需要我翻译成英文、做战术影响简析，还是整理欧冠名单注册规则与时间点？
