Sarky comments about new German squad? (4-2)
I believe the answer is:
line-up
'german squad?' is the definition.
Although both the answer and definition are singular nouns, I don't see how one could define the other.
'sarky comments about new' is the wordplay.
'sarky comments' becomes 'lip' (lip can mean sarcastic comments).
'about' is an insertion indicator.
'new' becomes 'neu' (I can't explain this - if you can you should give a lot more credence to this answer).
'lip' enclosing 'neu' is 'LINE-UP'.
Can you help me to learn more?
(Other definitions for line-up that I've seen before include "ID parade" , "Identity parade" , "Form a queue" .)
