Hence in the other goal (4)
I believe the answer is:
ergo
'hence' is the definition.
(I've seen this before)
'in the other goal' is the wordplay.
'in' indicates the answer is hidden within the clue.
'ERGO' is hidden within 'other goal'.
(Other definitions for ergo that I've seen before include "so philosopher wrote in Latin" , "'Cogito, ---- sum'" , "Hence" , "as a consequence" , "Therefore (Latin)" .)
