Serena should surpass 20 grand slam titles: Navratilova
SYDNEY (Reuters) - World number one Serena Williams shows no sign of slowing down with age and should win more than 20 grand slam singles titles, former great Martina Navratilova has said.
The 57-year-old Navratilova who won 18 grand slam singles titles, and 41 in women's and mixed doubles, is also confident the 32-year-old Williams will equal her singles haul at the Australian Open, which begins next week in Melbourne.
"If she can stay healthy there is no doubt she can go into the 20s, the sky is the limit," Navratilova told reporters in Adelaide where she will play in the World Tennis Challenge exhibition later on Tuesday.
"I know how hard it is once you get to 30, all those little niggling injuries get worse and it's much easier to have an off day.
"But still, she is in her 30s ... she is eager and winning is very contagious - once you get really used to it, you don't want to let go of it."
Australia's Margaret Court holds the overall record of 24 grand slam singles titles, while Germany's Steffi Graf won 22 titles in the Open era.
Williams is widely considered the best player of her generation and has been virtually unchallenged in the modern era, with her powerful game proving difficult to defuse for many counterparts on the WTA tour.
The American, however, has also been hampered by a number of serious injuries, including a knee injury in 2010 and cut foot that forced her to miss almost a year on the tennis circuit in 2010-2011.
