I just noticed this. I think it’s down to the fact that I tend to be a contrarian (or even meta-contrarian), and thus I usually side with the underdog, don’t particularly like those considered at the very top (also because of the said halo effect).
It just happens that Argentina produced some of those world-beaters, I think. And I still think their fame is not 100% justified.
LE. Also, if I think about it, I also enjoyed watching Ronaldinho a lot more than Messi. For some reason, Messi doesn’t score goals as memorable as Ronaldinho or Henry did, but maybe that’s just my biased brain.
