Caroline Wozniacki believes she is on her way back to the very top
It's been a while since Caroline Wozniacki has been at her best, but on her way to today's US Open semi-final against Angelique Kerber at Flushing Meadows she has certainly shown signs of the form that took her to World No.1 in 2010.
Wozniacki has been excellent, dropping just one set on her way to the last four - the first she played against American Taylor Townsend in the first round - and it's clear that the Dane is finding her way back to the top.
She knows it too. And that dream to return to the summit of the world rankings is still there, despite the fact that she now occupies 51st place.
Standing in her way of a first Grand Slam final since 2014 is her toughest test yet in the form of World No.2 Kerber, with the German able to go top of the rankings herself should she win the tournament.
It will be a big step up for Wozniacki from her previous opponents - her biggest scalp thus far has been eighth seed Madison Keys - but the former World No.1 says she is confident she can defeat anyone.
"I always believe in myself, no matter what my ranking," the 26-year-old said after her quarter-final win over Anastasija Sevastova.
"I've beaten pretty much everyone in the draw before.
"I still believe and feel that I am one of the top players. I'm just grinding my way back, and hopefully I'll have two more matches here."
