Left during no-score draw for City (6)
I believe the answer is:
oporto
'city' is the definition.
(city in Portugal)
'left during no-score draw' is the wordplay.
'left' becomes 'port' (left side of a ship - opposite of starboard).
'during' indicates putting letters inside.
'no-score draw' becomes 'OO' (the score 0-0).
'port' placed inside 'oo' is 'OPORTO'.
'for' is the link.
(Other definitions for oporto that I've seen before include "Portuguese wine city" , "Iberian city" , "European city" , "Portugal's second city" , "Wine city in Portugal" .)
