Is saga about tennis star? (6)
I believe the answer is:
agassi
'tennis star?' is the definition.
(I've seen this before)
'is saga about' is the wordplay.
'about' shows that the letters should be reversed in order.
'is'+'saga'='issaga'
'issaga' in reverse letter order is 'AGASSI'.
(Other definitions for agassi that I've seen before include "tennis star" , "Andre --, tennis champ" , "Andre --, tennis player" , "champion of the court?" .)
