Prove equal to the requirement of the would-be striker (5)
I believe the answer is:
match
'be striker' is the definition.
(a match can be struck)
I cannot understand how the rest of the clue works.
Can you help me to learn more?
(Other definitions for match that I've seen before include "Marriage; game" , "Equal contender" , "Game - pairing - lucifer" , "An exact duplicate or a contest between two" , "Fixture - fit with - smoker's aid" .)
