Retired soccer ace disinclined to accept cocktail (7)
I believe the answer is:
sidecar
'cocktail' is the definition.
(I know that Sidecar is a type of cocktail)
'retired soccer ace disinclined to accept' is the wordplay.
'retired' says the letters should be written backwards.
'to accept' says the answer is hidden in the clue.
'racedis' is hidden in the letters of 'soccer ace disinclined'.
'racedis' back-to-front is 'SIDECAR'.
(Other definitions for sidecar that I've seen before include "Tipple" , "Where a passenger may go" , "Alcoholic drink" , "Cocktail of brandy, orange liqueur and lemon juice" , "Motorcycle add-on" .)
