Martina Navratilova says it is hard to see Roger Federer retaking the No. 1 ranking. Federer lost to Novak Djokovic in the semifinals of Indian Wells.

"Roger is on the other side of the float, I don't think he'll ever play as well as he did three or four years ago—that's not to say he can't still win a slam, but it's difficult to see him climbing back to No. 1," Navratilova said. "Nadal is dominating and Djokovic's confidence is off the chart. Roger has lost three matches (this season) to Djokovic and lost to him at U.S. Open last year as well, it will get under his skin."—Matthew Cronin
