Passes into net won cups (3-3)
I believe the answer is:
one-two
'net won cups' is the definition.
The definition suggests a singular noun which matches the answer.
I can't explain the rest of the clue.
Can you help me to learn more?
(Other definitions for one-two that I've seen before include "Soccer move" , "Interpassing at football - left-right at boxing" , "Swift couple of blows at boxing" , "Pair of punches with both hands in quick succession" , "Boxing or soccer manoeuvre" .)
