Superior Italy in match with English (5)
I believe the answer is:
liege
'superior' is the definition.
(feudal term for one's superior)
'italy in match with english' is the wordplay.
'italy' becomes 'i'.
'in' indicates putting letters inside.
'match' becomes 'leg' (leg can mean a sports match).
'with' is a charade indicator (letters next to each other).
'english' becomes 'e' (abbreviation).
'i' placed within 'leg' is 'lieg'.
'lieg'+'e'='LIEGE'
(Other definitions for liege that I've seen before include "Subject in history" , "Belgian province" , "Loyal subject" , "old lord" , "Faithful," .)
