Andre of tennis (6)
I believe the answer is:
<span class="explanation-format__ClueExplanation">'<span class="explanation-format__original">andre of tennis</span>' is the definition.<br/ ><span class="explanation-format__explanation">(I've seen this in another clue)</span><br/ ><br/ >This is all the clue.<br/ ></span>
(Other definitions for agassi that I've seen before include "tennis star" , "Andre --, tennis champ" , "Andre --, tennis player" , "champion of the court?" .)
