I've made an updated graphic based on feedback. Thanks to @nooeh@lemmy.world for the critique. Updated graphic here:

Is Son one of the best finishers EVER? Let's look at some data. 👇
We use actual goals minus expected goals (xG) as a proxy for finishing skill. Players who consistently score more than their xG means they are scoring goals other players would miss. Generally, only the most elite goalscorers *consistently* outperform their xG.
And I can find no player who consistently beats Son. It's astonishing.
Can you find anyone better at elite level?
I've redone it with a little more care (see above) and agree the summing of xG over performance wasn't a good idea. It was a vestigial artefact where I'd been mucking about and I wish I'd removed it, but it was late and I couldn't be bothered as it didn't really affect the point I was making and it's not intended to be rigorous maths.
The results in the updated version aren't significantly different apart from Messi. The reason Messi's over performance has shifted so much in the update is because I removed the three PSG and MLS years, which I think are an unfair reflection on him.
I don't agree averaging the xG overperformance "grossly" inflated the numbers (unless you consider 6% gross). I do agree including the PSG and MLS years grossly short changes Messi, but I noted something to that effect in the original.
You don't need to be quite so hostile to people sharing their stuff here btw - save that for Twitter or Reddit if hostilities float your boat. I take it you're not and have never been an educator? But no harm done - thx for the feedback - it was useful and improved the analysis :)
You're right, I am sorry about being hostile. I should have been more light hearted about it. I just thought that it's another hyperbolic post contriving to exxagerate how good a player is, just like a lot of Twitter posts.
However, I disagree that cherry picking data would improve your analysis. Include all the years, but weight them properly (as the overall G/xG would).
Keep up the OC. Sorry again and cheers!
Do you know where I can get xG data before 2017? That's where FBref stops.
I just googled it for Messi. I assume it's available for a smattering of top forwards.
