Brazilian great coming back to plague United pulled out big game (8)
I believe the answer is:
elephant
'game' is the definition.
The answer and definition can be both animals as well as being singular nouns.
Perhaps you can see a link between them that I can't see?
I cannot understand how the remainder of the clue works.
Can you help me to learn more?
(Other definitions for elephant that I've seen before include "The plane (anag.)" , "Largest land mammal" , "Large animal (in the room?)" , "Large land mammal" , "Trumpeting animal" .)
