As an American, I am deeply ashamed by the answer of my fellow American. I don't know who Aguero is either, I looked up and he's a very handsome Argentine soccer player, well, I can tell you, I've studied at school a lot about wars, among those the Falklands (or as you call them Melvinas War). I think British people have overcome it and relationships between both countries are stable now.
As for the soccer issues, once the referee ends the match, it all comes to an end. Period.
Kind regards from AL.
