I see attack repelled by Italian champions (6)
I believe the answer is:
napoli
'i see attack repelled by italian champions' is the definition.
I can't tell whether this definition defines the answer.
'i see attack repelled by' is the wordplay.
'see' becomes 'lo' (archaic exclamation meaning 'look!').
'attack' becomes 'pan' (pan can mean to attack or criticise).
'repelled' says the letters should be written backwards.
'by' says to put letters next to each other.
'lo'+'pan'='lopan'
'lopan' backwards is 'napol'.
'i' put after 'napol' is 'NAPOLI'.
Can you help me to learn more?
(Other definitions for napoli that I've seen before include "Decline" , "Italian city" , "Mediterranean city" , "Italian name for Naples" .)
