Wrestling for money and love (4)
I believe the answer is:
sumo
'wrestling' is the definition.
(I've seen this before)
'money and love' is the wordplay.
'money' becomes 'sum' (I've seen this before).
'and' is a charade indicator (letters next to each other).
'love' becomes 'o' (love means zero in tennis).
'sum'+'o'='SUMO'
'for' acts as a link.
(Other definitions for sumo that I've seen before include "Japanese wrestling sport of over-weight men" , "Japanese form of wrestling" , "Japanese wrestling for huge men" , "foreign form of fighting" , "Style of traditional Japanese wrestling" .)
