Salah is a fan favourite and media darling (feck knows why) so he gets the benefit of stats being selected in his favour and narratives being constructed around those stats. I've studied statistics at uni level and it's true that you really can use stats to spin almost any narrative you want.
You won't see a comparison of 2019/20 PL G/xG (the gold standard quantitative measure of clinical finishing) in a conversation about Salah because he wasn't even in the top 10 this season. Kane, Ings and Auba were the top 3, if I remember correctly, and it wasn't particularly close. Sterling was more clinical than Salah..
Anyway, it always annoyed me when, at the end of Salah's first PL season, almost everyone was already hailing him as world class, best in the league, and so on. Kane had to do it for three straight seasons to receive accolades that still weren't as enthusiastic. I said at the end of that season that Salah was incredibly lucky to take the PL all-time record and that he'd never come close again. So far I've had no cause to rethink.
A great player who's dining out more on his team's reputation and one phenomenal breakout season than his everyday ability. Would be more realistically rated if he played for Spurs because Son would show him up.
