Stole nuts from the bottom and left quickly (8)
I believe the answer is:
snaffled
'stole' is the definition.
(snaffle can mean to steal or take)
'nuts from the bottom and left quickly' is the wordplay.
'nuts' becomes 'fans' (nut can mean a fan or supporter).
'from the bottom' says the letters should be written backwards (in a down clue, letters come from the bottom).
'and' means one lot of letters go next to another.
'left quickly' becomes 'fled' (to flee is to run away).
'fans' in reverse letter order is 'snaf'.
'snaf'+'fled'='SNAFFLED'
(Other definitions for snaffled that I've seen before include "Stolen" , "secured quickly" .)
