Team will reportedly move furtively (5)
I believe the answer is:
sidle
'move furtively' is the definition.
(I've seen this before)
I can't explain the remainder of the clue.
(Other definitions for sidle that I've seen before include "'Move sideways, furtively perhaps (5)'" , "Move in furtive or timid manner" , "sidewalk" , "Walk sideways like crab" , "Slide (anag.)" .)
