Congrats, but I hope you understand that I don't care.
The German team already entered the rebuilding phase. I am glad that it happens that early, even though we will have to witness a few more games like today (but I doubt many other national teams cam generally play on the same level as GER and ARG, those two teams were in the final for a reason). Games like today keeps the world champion on their toes and makes the new gen competitive for Euro 2016 in the long run.
What this game proved though is the fact that it isn't best idea to sell Di Maria, to put it mildly. Real will miss him, in fact they already do...
