Refuses to play against every international team (3,6)
I believe the answer is:
all blacks
'international team' is the definition.
(New Zealand national rugby union team)
'refuses to play against every' is the wordplay.
'refuses to play' becomes 'blacks' (as in blacking or boycotting a film).
'against' means one lot of letters go next to another.
'every' becomes 'all' (similar in meaning).
'blacks' put after 'all' is 'ALL BLACKS'.
(Other definitions for all blacks that I've seen before include "The New Zealand national rugby team" , "as needed for optimal break" , "New Zealand's great rugby team" , "international players" , "Colourless New Zealand rugby team?" .)
