US Open finalist Angelique Kerber says that being able to call herself the new world number one "sounds amazing".
Kerber, 28, beat Caroline Wozniacki in her semi-final as current number one Serena Williams lost against Karolina Pliskova to end 186 weeks at the top.
Germany's Kerber will officially become her country's first number one since Steffi Graf in 1996 when the new rankings are released next week.
"To be number one in the world sounds amazing." said second seed Kerber.
"For me it's amazing to be, after Steffi, the number one player from Germany," added Kerber, who is also the first German singles player to reach a US Open final since Graf in 1996.
