Team with an air of superiority (4)
I believe the answer is:
side
'team' is the definition.
(both can mean a sports team)
I cannot understand how the rest of the clue works.
Can you help me to learn more?
(Other definitions for side that I've seen before include "Bank" , "Manchester United, for example?" , "Ides (anag.)" , "Team; facet" , "Edge - aspect - team" .)
