超越卡西，贝林厄姆以22岁128天刷新欧冠50场最年轻纪录（贝林厄姆22岁128天达成欧冠50场，超卡西成史上最年轻）

Calculating UCL appearances

I’m working out some dates here: adding 22 years and 128 days to June 29, 2003, gives me November 4, 2025. That’s likely when the UCL group match would be. I’m wondering if someone could surpass Iker Casillas as the youngest player to reach 50 UCL appearances. Casillas hit that milestone at just 22 years and 297 days. It seems Kylian Mbappé might approach that but probably won't reach it earlier than Casillas. It's worth checking those stats!Clarifying Champions League appearances

I'm recalling that Mbappé reached 50 Champions League appearances around November 2021 at age 22 years and 306 days. I wonder how qualifying matches fit into this: usually, only the group stage counts for those stats. Mbappé started in the 2016-2017 season with Monaco, and by 2021, he hit that milestone. I think Iker Casillas may still hold the record as the youngest for 100 appearances. It seems like providing options for a social media post would be a good idea, including various headline suggestions and concise summaries.Crafting Chinese options

I’m following the style guidelines and plan to respond in Chinese with concise options. I’ll avoid heavy formatting and offer three headline variants along with an English translation. Here’s what I’m thinking:

• 标题优化：3 options
• 英文翻译： "Bellingham breaks the record as the youngest player to reach 50 UEFA Champions League appearances at 22 years and 128 days, surpassing Iker Casillas."
• 简短社媒文案： I’m considering a short social media post but avoiding emojis since they aren’t ASCII.

I’ll also ask if the user wants source verification or needs me to write a short news piece or tweet. Let's produce that!
