New Delhi, Dec 09 (ANI): The sorry state of American men's tennis will continue for some time with no real talent on the horizon, said Pete Sampras who dominated the game in the 1990s with fellow American Andre Agassi. No American has won a men's grand slam singles title since Andy Roddick triumphed at the 2003 US Open and only five of them feature in the top 100 with John Isner highest at 19th. Tennis legend said that it will be quite a while to see American tennis back to where it was years back.
