Backing for official nabbing team's dodgy dealer? (5)
I believe the answer is:
fixer
'dodgy dealer?' is the definition.
The definition suggests a singular noun which matches the answer.
'backing for official nabbing team's' is the wordplay.
'backing for' is a reversal indicator.
'official' becomes 'ref' (match official in football, say).
'nabbing' is an insertion indicator.
'team' becomes 'XI' (a football team, from Roman numerals for 11).
'ref' placed around 'xi' is 'rexif'.
'rexif' back-to-front is 'FIXER'.
Can you help me to learn more?
(Other definitions for fixer that I've seen before include "Agent" , "One who makes arrangements" , "Chemical in photography" .)
