Bury Football Club at home in San Siro (5)
I believe the answer is:
inter
I believe this is a double definition.
'bury' is the first definition.
(to inter is to put into the ground)
'football club at home in san siro' is the second definition.
(I've seen this before)
(Other definitions for inter that I've seen before include "Put into the ground" , "Set deep" , "Football Club seen in Milan" , "Bury (or, perhaps, Milan)" , "Milan FC" .)
