Analyzing the U23 Rule Change

I'm considering the recent U23 rule change in 2023. I can ask the user if they’d like a quick background and tactical analysis or if they prefer me to verify the report. I plan to share a short confirmation that it's a rumor, based on my knowledge cutoff, along with basic context and what to expect tactically. I’ll keep it friendly and concise while ensuring there's no misinformation since it's a harmless sports rumor.

I can provide key details about Nick Montgomery's status and relevance for Beijing Guoan as well.
