She has great potential (5)

I believe the answer is:

greta

'she' is the definition.

'great potential' is the wordplay.
'potential' is an anagram indicator (another potential order of the letters).
'great' is an anagram of 'GRETA'.

'has' acts as a link.

(Other definitions for greta that I've seen before include "Miss Garbo" , "Female" , "The familiar Ms Garbo, solitary film star" , ".....Garbo, who wanted to be alone" , "Girl" .)

I've seen this clue in the Evening Standard.
