With regular saves on field, no goals (3)
I believe the answer is:
nil
'with regular saves on field' is the definition.
I can't judge whether this definition defines the answer.
'no goals' is the wordplay.
'no' becomes 'n' (common abbreviation).
'goals' becomes 'il' (I am not sure about this - if you are sure you should believe this answer much more).
'n'+'il'='NIL'
Can you help me to learn more?
(Other definitions for nil that I've seen before include "Love" , "Nothing, zilch" , "Zero, no score" , "duck" , "Nix, nada, nothing" .)
