I came across this the other day.
Where have you gone Steffi Graf? A nation of tennis fans turn their lonely eyes to you.
This line is borrowed and changed from the song" Mrs Robinson "by Paul Simon
The line in that song is Where have you gone Joe Dimaggio?
means basically Where have the heroes gone?
Joe Dimaggio was a baseball player who surpassed the athletic world to become an American cultural icon.
A hero on and off the field of play. The song is a commentary about family, society, and disillusion regarding political fiqures.
This sums up perfectly to me what happened when Steffi left the game and the state of the women's game.
