What creates atmosphere in stadium: header for Man United saved by defender thus (10,5)
I believe the answer is:
background music
'what creates atmosphere' is the definition.
I can't tell whether this defines the answer.
'stadium header for man united saved by defender thus' is the wordplay.
I cannot really understand how this works, but
'stadium' could be 'ground' (eg a football ground) and 'ground' is located in the answer.
'man' could be 'si' and 'si' is present in the answer.
'united' could be 'u' (as in Man U, Manchester United) and 'u' is found within the answer.
'defender' could be 'back' (left-backs and right-backs are football defenders) and 'back' is located in the answer.
This may be the basis of the clue (or it may be nonsense).
'in' is the link.
Can you help me to learn more?
(Other definitions for background music that I've seen before include "atmospheric enhancement" , "Muzak" .)
