Sport needing money getting nothing (4)
I believe the answer is:
sumo
'sport' is the definition.
(I've seen this before)
'money getting nothing' is the wordplay.
'money' becomes 'sum' (I've seen this before**).
'getting' means one lot of letters go next to another.
'nothing' becomes 'o' (looks like zero - 0).
'sum'+'o'='SUMO'
'needing' acts as a link.
(Other definitions for sumo that I've seen before include "Jap. wrestling" , "Japanese wrestling with big fat men" , "one of the martial arts" , "Kind of wrestling" , "Japanese wrestling sport of over-weight men" .)
