Eats with the best (6)
I believe the answer is:
champs
'eats' is the definition.
The definition and answer can be both related to consumption as well as being verbs in their -s form.
Maybe there's an association between them I don't understand?
I don't understand the rest of the clue.
Can you help me to learn more?
(Other definitions for champs that I've seen before include "Munches noisily like abbreviated winners" , "Title holders" , "Munches noisily like horse at bit" , "Heaven in Paris?" , "frets impatiently" .)
