Interpreting a phrase

I’m trying to decipher what "战旧主" means. It seems to imply playing against a former club, but Guirassy used to play for Köln, not Dortmund, so that could be incorrect. Though he’s currently at Stuttgart, "旧主" might refer to him facing his old manager or something similar. The user might expect some lineup info or a preview. I should respond in Chinese, asking if they want首发名单, 比分预测, or 直播链接? I'll make sure not to fabricate any information.Clarifying user intent

I noticed that while harness approvals have been described, the sandbox settings weren't mentioned, so I'm going to assume the defaults are in place: workspace-write, network enabled, and approvals on-failure. The user just posted a headline, so I should clarify their needs. I can offer options like 首发名单整理 or 比分预测, all in Chinese. There's also some ambiguity with "小贝林," so I should ask whether they mean 贝林厄姆 or 拜诺-吉滕斯. Asking for confirmation about “吉拉西战旧主” is also a good idea, but I want to keep it concise.
