Teams with wings (5)
I believe the answer is:
sides
I believe this is a double definition.
'teams' is the first definition.
(eg football sides)
'wings' is the second definition.
(I've seen this in another clue)
'with' acts as a link.
(Other definitions for sides that I've seen before include "Teams or flat surfaces" , "Sports teams" , "opponents?" , "Flanks, or opposing teams" , "More than one team" .)
