The disadvantage of inexperienced defender against Germany? (8)
I believe the answer is:
drawback
'the disadvantage' is the definition.
(drawback is a kind of disadvantage)
'inexperienced defender against germany?' is the wordplay.
'inexperienced' becomes 'raw' ('raw' can be similar in meaning to 'inexperienced').
'defender' becomes 'back' (I've seen this in other clues).
'against' means one lot of letters go next to another.
'germany?' becomes 'd' (international vehicle registration code).
'raw'+'back'='rawback'
'rawback' after 'd' is 'DRAWBACK'.
'of' acts as a link.
(Other definitions for drawback that I've seen before include "Disadvantage, problem" , "Hindrance - disadvantage" , "Hindrance - retreat" , "Catch" , "Limitation, disadvantage" .)
