Soccer's "Black Pearl” (4)
I believe the answer is:
pele
'soccer's black pearl' is the definition.
(I've seen this in another clue)
This is the entire clue.
(Other definitions for pele that I've seen before include "Brazilian footballer, scored over 1000 goals" , "Brazilian World Cup footballer" , "Brazilian footballer, Edison Arantes do Nascimento" , "Famous Brazilian footballer" , "Brazil's hero" .)
