Perhaps Russian girl's goal abroad (4)
I believe the answer is:
olga
'perhaps russian girl's' is the definition.
(common Russian name)
'goal abroad' is the wordplay.
'abroad' indicates an anagram.
'goal' anagrammed gives 'OLGA'.
(Other definitions for olga that I've seen before include "Could be Russian girl" , "Slavic girl's name" , "Lady" , "Russian girl's name, anagram of ..." .)
