I'm not expecting an easy game at all, but I think we are going to make it. My tip is 2:0 with a goal some time in the first half and a second one towards the end when we play a good counter attack.
What I'm almost certain of is: If Argentina wins, they win 1:0 or in penalty shootout. They will play with a very defensive set, the connection between midfield and Messi/Higuain is somewhat lacking. So they won't have many chances. I expect a similar game as vs NL, just that our team will be more dangerous offensively and put a bit higher pressure on Argentina in general, while it will still be hard to break through.
It's time. I have not experienced a won world championsship for Germany in my lifetime. I really want it to happen. We have an awesome generation of football players with many of them playing their last world cup. The team is on it's peak not only in skill, also in experience. I really admire them for their great team spirit and for realizing that is the last big opportunity with this generation. The final being lost 2002, the end in the semi-finals 2006 & 2010, always close but never there.
Time has come. We have to win tomorrow.
