Tennis champion almost gets nothing (4)
I believe the answer is:
nada
'nothing' is the definition.
(synonyms)
'tennis champion almost' is the wordplay.
'tennis champion' becomes 'nadal' (I've seen this before).
'almost' means to remove the last letter (almost the whole word is kept).
'nadal' with its final letter taken off is 'NADA'.
'gets' is the link.
(Other definitions for nada that I've seen before include "Love" , "Not a sausage" , "zip" , "Nothing (US)" .)
