Considering goalkeeping stats

I’m thinking about how different sources can show varied stats, like PL-only versus all competitions, goals versus shots, and domestic versus European contexts. I want to pull reliable numbers from Opta or the Premier League site to back up anything I say. It could be helpful to mention that Onana’s sample size is small and that stats can’t fully capture aspects like shot-stopping. I’m also noting how to present this in simple Chinese, possibly with a bullet list. Let's create that!
