Team magazine (7)
I believe the answer is:
arsenal
I believe this clue is a double definition.
'team' is the first definition.
(Arsenal football club)
'magazine' is the second definition.
(I've seen this before)
(Other definitions for arsenal that I've seen before include "Store of guns and ammunition" , "Weapon store - team" , "London FC" , "Supply of weapons" , "Store of weaponry" .)
