Without competition, unable to compete? (9)
I believe the answer is:
matchless
I believe this is a double definition.
'without competition' is the first definition.
('competition' can be 'match' (match is a kind of competition) so maybe 'without competition' can be ''matchless')
'unable to compete?' is the second definition.
(having no matches to play)
(Other definitions for matchless that I've seen before include "Incomparable" , "Without peer, nonpariel" , "team without a fixture" , "Having no equal" , "Second to none" .)
