Team in United, I see, going up (4)
I believe the answer is:
side
'team' is the definition.
(I've seen this before)
'in united i see going up' is the wordplay.
'in' says the answer is hidden in the clue.
'going up' shows that the letters should be reversed in order.
'edis' is hidden within 'united i see'.
'edis' in reverse letter order is 'SIDE'.
(Other definitions for side that I've seen before include "Position to the right or left of" , "Edge - aspect - team" , "faction" , "Team - border" , "Manchester United, for example?" .)
