官方：意大利裁判圭达将执法欧冠阿森纳vs拜仁（官方确认：意大利名哨圭达将吹罚欧冠阿森纳对阵拜仁）

Drafting news blurb

I want to provide a concise news blurb about Marco Guida, the Italian referee appointed to officiate the Arsenal vs. Bayern match in the UCL. I should ask if the user wants more details, like timing or context. Even though I don't have network access, I can offer a brief Chinese news flash along with a one-line background on Guida. I'll summarize him as an Italian referee born in 1981 and a FIFA referee since 2014, which seems correct, but I don't want to overcomplicate things.Creating concise news update

I think it's best to avoid adding extra facts unless the user requests them. I'll format the brief update in Chinese as: 标题; 内容: 欧足联官方宣布... I should mention the match as 欧冠阿森纳对阵拜仁的比赛 without making assumptions about the specific stage. It could be the quarterfinals or group stage, but I want to keep it general for safety. I'll mention that I can provide more details like the referee crew, kickoff time, or historical matchups if they'd like. Keeping it concise!
