This is a pic I found while searching and found it on a website about cometogermany.com i think. Can you make say a girl dressed similarly with a soccer ball either in the hands above the head or at the feet? Make a girl with a soccer uniform on in Germany's colors with a soccer ball. Or another idea playing on the "waving" German flag, add a soccer ball to look like it was rolling over the waves. Or perhaps a twisted boutique bow with a soccerball resin in the middle. Or use soccer ball printed ribbon like I see at Wally World all of the time and integrate it with Germany's colors for a bow.
Hope this helps.
