Therefore in another goal (4)
I believe the answer is:
ergo
'therefore' is the definition.
(thesaurus)
'in another goal' is the wordplay.
'in' indicates a hidden word.
'ERGO' is hidden in the letters of 'another goal'.
(Other definitions for ergo that I've seen before include "for this reason" , "so philosopher wrote in Latin" , "Therefore (Latin)" , "Consequently" , "'Therefore, to the old Romans (4)'" .)
