This team has a pretentious air (4)
I believe the answer is:
side
I believe this is a double definition.
'this team' is the first definition.
(both can mean a sports team)
'a pretentious air' is the second definition.
(I've seen this before)
'has' is the link.
(Other definitions for side that I've seen before include "English" , "Spin given to a ball by striking it off-centre" , "TV channel" , "party" , "Flank; sports team" .)
