Disadvantage of defender pursuing 0-0? (8)

I believe the answer is:
drawback
'disadvantage' is the definition.
(drawback is a kind of disadvantage)
'defender pursuing 0-0?' is the wordplay.
'defender' becomes 'back' (left-backs and right-backs are football defenders).
'pursuing' says to put letters next to each other.
'0 0?' becomes 'draw' (I am not sure about this - if you are sure you should believe this answer much more).
'back' put after 'draw' is 'DRAWBACK'.
'of' acts as a link.
Can you help me to learn more?
(Other definitions for drawback that I've seen before include "Hindrance - disadvantage" , "Disadvantage, problem" , "Catch" , "Limitation, disadvantage" , "Hindrance - retreat" .)
