Overnight cobbler of the German football team (3)

I believe the answer is:
elf
This clue could be a double definition.
'overnight cobbler' is the first definition.
The definition and answer can be both people as well as being singular nouns.
Maybe you can see a link between them that I can't see?
'german football team' is the second definition.
Although both the answer and definition are singular nouns, I don't understand how one could define the other.
'of the' acts as a link.
Can you help me to learn more?
(Other definitions for elf that I've seen before include "A leprechaun" , "He causes mischief" , "Imp-like being" , "One of the little folk" , "1 ac fairy" .)
