Fan wants victory immediately (6)
I believe the answer is:
winnow
'fan' is the definition.
(winnowing is a kind of fanning)
'victory immediately' is the wordplay.
'victory' becomes 'win' (I've seen this before).
'immediately' becomes 'now' (I've seen this before).
'win'+'now'='WINNOW'
'wants' is the link.
(Other definitions for winnow that I've seen before include "Dehusk grain using air currents" , "Blow air through (grain) to remove chaff" , "Sift out" , "Separate the wheat from the chaff" , "Separate chaff from grain" .)
