I believe the answer is:

omnivore

I'm a little stuck... Click here to teach me more about this clue!

'maybe goat' is the definition.
(I know that ric Maxim Choupo-Moting is a human)

I don't understand the rest of the clue.

Can you help me to learn more?

(Other definitions for omnivore that I've seen before include "I'll take in anything" , "Unfussy eater" , "Not a fussy eater!" , "who'll swallow anything?" , "One eating every food" .)

I've seen this clue in the Sydney Morning Herald.
