Bury FC at home in San Siro (5)
I believe the answer is:
inter
'bury' is the definition.
(to inter is to put into the ground)
'fc at home in san siro' is the wordplay.
I cannot quite understand how this works, but
'at' could be 'in' (synonymous in some cases - eg at school, in school) and 'in' is present in the answer.
This may be the basis of the clue (or it may be nonsense).
Can you help me to learn more?
(Other definitions for inter that I've seen before include "Prefix for between - bury it" , "Milan football team" , "Football Club seen in Milan" , "Put into the ground" , "an Italian soccer team?" .)
