On top, man turned against former European (8)
I believe the answer is:
yugoslav
'former european' is the definition.
(I've seen this before)
'on top man turned against' is the wordplay.
I cannot really see how this works, but
'man' could be 'ugo' and 'ugo' is found within the answer.
'against' could be 'v' (abbreviation for 'versus') and 'v' is present in the answer.
This may be the basis of the clue (or it may be nonsense).
Can you help me to learn more?
(Other definitions for yugoslav that I've seen before include "Balkan native" , "former statesman" , "Old East European" , "Former Belgrade native" , "from Croatia?" .)
