Woman gets excellent sheep back (5)
I believe the answer is:
maria
'woman' is the definition.
'excellent sheep back' is the wordplay.
'excellent' becomes 'ai' (resembles 'A1', old-fashioned term for excellent).
'sheep' becomes 'ram' (male sheep).
'back' says the letters should be written backwards.
'ai'+'ram'='airam'
'airam' back-to-front is 'MARIA'.
'gets' is the link.
(Other definitions for maria that I've seen before include "Woman" , "Black --, police van" , "Italian Mary" , "musical" , "one from West Side Story" .)
