Eh, that's on Madrid for selling him even though he probably is Madrid quality TBH. His season at Sociedad and what he's shown at Arsenal both convey a player good enough to play for Madrid.
But also, I think they bought 16 year old "next big thing" anticipating they could conceivably sell him down the line, similar to what Chelsea do with 17- and 18- year olds.
And none of this negates the overarching point, which is that - for a 16 year old "wonderkid" in the age of social media and intense 24/7 scrutiny - the kid has done great.
And, it's not as if either Barcelona OR PSG envisioned Xavi Simons breaking out at PSV rather than at either of them. Sometimes shit happens!
