8-time Grand Slam winner Andre Agassi discusses what American players need to win major tournaments

It's been over two decades since an American men's tennis player won a Grand Slam, but Andre Agassi thinks the drought could end soon.

Agassi and Andy Roddick both took home a Grand Slam in 2003, but the United States has come up empty-handed ever since.

Roger Federer, Rafael Nadal and Novak Djokovic have since taken over the sport, rewriting the history books in the process. Pete Sampras won all 14 of his Grand Slams before those three even won their first.

Since then, all they've done is blow by Sampras.
