Team's arrogance (4)
I believe the answer is:
side
This clue is a double definition.
'team's' is the first definition.
(I've seen this before)
'arrogance' is the second definition.
(I've seen this before)
(Other definitions for side that I've seen before include "Edge - aspect - team" , "Spin given to a ball by striking it off-centre" , "Sporting team" , "Ides (anag.)" , "long forgotten" .)
