Mischievous character shown by German soccer team? (3)
I believe the answer is:
elf
This clue is a double definition.
'mischievous character' is the first definition.
(mischievous creature in folklore)
'german soccer team?' is the second definition.
('elf' is eleven in German)
'shown by' is the link.
(Other definitions for elf that I've seen before include "Mischievous youngster" , "1 ac fairy" , "Supernatural creature of folk tales" , "A small sprite with magic powers" , "'Pixie, imp (3)'" .)
