Dude, we have something in common. I'm not German but my grandfather really loves Germany. Really has influenced me to support Germany #2 after the US and I really love the country. He loves absolutely everything about Germany for some reason even though he has never stepped foot in it lol. He has been watching and rooting for Germany since he was a teen many years ago. Tells me stories about Beckenbauer and other players of the past. Has also influenced me to love soccer as well.
I'm sorry to hear about your grandfather. I was very fortunate to have my grandfather with me to see them win it. Not as fortunate when he was happy to see Germany beat USA in the WC
. Like I said, he REALLY loves Germany.
So, if you are talking about national teams, USA #1, Germany #2. After that, nothing really.
