Left in team to move unobtrusively (5)
I believe the answer is:
sidle
'move unobtrusively' is the definition.
(I've seen this in another clue)
'left in team' is the wordplay.
'left' becomes 'l' (common abbreviation).
'in' indicates putting letters inside.
'team' becomes 'side' (both can mean a sports team).
'l' put inside 'side' is 'SIDLE'.
'to' is the link.
(Other definitions for sidle that I've seen before include "Slide (anag.)" , "Walk stealthily" , "sidewalk" , "Walk crabwise" , "Inch along" .)
