Italian scorer in libel wrangle (7)
I believe the answer is:
bellini
'italian scorer' is the definition.
'bellini' can be an answer for 'scorer' (I've seen this before). I also know that 'italian' relates to this answer.
'in libel wrangle' is the wordplay.
'wrangle' is an anagram indicator.
'in'+'libel'='inlibel'
'inlibel' anagrammed gives 'BELLINI'.
(Other definitions for bellini that I've seen before include "Italian composer of operas such as Norma (1831)" , "Italian opera composer (Norma)" , "Champagne and peach cocktail" , "Musical artist" , "drink" .)
