Penalty or not, i don't think it would have made such a big difference, and a 1-1 would not have been the real honnest value for this game. Same for the 4-0 against Argentina.
Spain was much better and deserved to win, and I'm very happy about that. The final will be more refined with Spain I hope.
Funny to see how football is really a matter of "mood of the day/moment". One day Germany plays a good game and win 4-0 against a normally better Argentina (considering the rest of the games 2 teams played during this WC), and the next day Germany loose against Spain who didn't showed us much greats during this WC.
Anyway, congrats for the Germans, they gave us some nice football moments! But it was time for them to go home. Winning the WC would not have been so great for a team who lost 0-1 against Serbia during the tournament anyway.. 
Real gold cannot be seen or even touched, it has to be listened & felt with the heart..
