Deserve Ashes trophy, did you say? (4)
I believe the answer is:
earn
'deserve' is the definition.
(I've seen this before)
'ashes trophy did you say?' is the wordplay.
'ashes trophy' becomes 'urn' (I've seen this before).
'did you say?' indicates a 'sounds like' (homophone) clue.
'urn' is a homophone of 'EARN'.
(Other definitions for earn that I've seen before include "Deserve - merit" , "net" , "Acquire money by labour" , "Gain through labour or work" , "Take in bread" .)
