Surplus pasty for one in Old Trafford team (8)
I believe the answer is:
unwanted
'old trafford team' is the definition.
I can't judge whether this defines the answer.
'surplus pasty for one' is the wordplay.
'surplus pasty' becomes 'wanted' (I can't explain this - if you can you should believe this answer much more).
'for' is a charade indicator (letters next to each other) (I've seen this in other clues).
'one' becomes 'un' (northern English dialect form of 'one').
'wanted' put after 'un' is 'UNWANTED'.
'in' is the link.
Can you help me to learn more?
(Other definitions for unwanted that I've seen before include "Superfluous" , "Not required" , "Not needed" , "Outcast" , "Left over" .)
