Singer recalls decisive win at football? (6)
I believe the answer is:
linnet
'singer' is the definition.
(linnet is a kind of birdanimal)
'recalls decisive win at football?' is the wordplay.
'recalls' shows that the letters should be reversed in order (I've seen 'recalled' mean this).
'decisive win at football?' becomes 'tennil' (a 10-0 victory).
'tennil' backwards is 'LINNET'.
(Other definitions for linnet that I've seen before include "Winger" , "Type of finch" , "Bird in the finch family" , "Songbird (to 6 18)" , "Songbird in Lent" .)
