It's all about perspective, wich depends on where you are born and where you live.
For us south american people, Libertdores has a fantastic history with many memorable matchs and finals, we've always dreamd about the day that we would have this kind of license on a big football franchise as PES, and PES always had our attention even more than Fifa here in South America, wich it seems to be not the case in Europe, hence why we are getting this attention from Konami, we deserved it.
From about a decade ago, we south americans couldn't care less about the Premier League, it was just as exotic (as you said) as the Ukranian League, in European scenario it was all about the Spanish or Italian League where our best south american idols (Ronaldo, Romário, Rivaldo, Caniggia and etc) used to play. We never cared about any big english club, we didn't know much about them in comparison to clubs like Barcelona, Real Madrid, Inter, Milan and etc, so the english was very exotic and uninteresting for us in a recent past. Just because we didn't hear much about the English League does that mean that it was a bad league that didn't deserve our attention ? I don't think so.
