Talk about defender getting revenge (7)
I believe the answer is:
payback
'revenge' is the definition.
(I know that payback is a type of revenge)
'talk about defender getting' is the wordplay.
'talk about' becomes 'pay' (I am not sure about this - if you are sure you should believe this answer much more).
'defender' becomes 'back' (left-backs and right-backs are football defenders).
'getting' means one lot of letters go next to another.
'pay'+'back'='PAYBACK'
Can you help me to learn more?
(Other definitions for payback that I've seen before include "Profit" , "return on investment" , "Financial return" , "act of revenge" .)
