Nothing, love (3)
I believe the answer is:
nil
I believe this clue is a double definition.
'nothing' is the first definition.
(eg nil is zero in football)
'love' is the second definition.
(love and nil mean zero in cricket and football)
(Other definitions for nil that I've seen before include "0" , "Nothing, zilch" , "duck" , "Love" , "Non-existent" .)
