Incentives to win them?
I believe the answer is:
spurs
'incentives' is the definition.
(I've seen this before)
I cannot understand how the remainder of the clue works.
Can you help me to learn more?
(Other definitions for spurs that I've seen before include "Gives encouragement to" , "Goads" , "incentives" , "Kicks out" , "soccer team" .)
