Thats all tied to the history with the Argies from the 80s, hand of god and the falklands
If you haven't read it, the Jonathan wilson book, angels with dirty faces, about the history of football in argentina, is really good. Goes into how the culture breeds so called 'Angels with dirty faces', which is a translated saying from down there, I believe it's sort of meaning angel with a devils face
Basically means they create these angelic type of skilled players like diego, riquelme, Batistuta, all the way back to di Stefano, but they all have that devil inside of them who brings out a stamp here and there when they see the red mist
