Britain's Johanna Konta is targeting the world number one ranking after claiming the biggest title of her career at the Miami Open.
The 25-year-old British number one beat Caroline Wozniacki 6-4 6-3 to claim £940,000 in prize money and is set to climb to seventh in the world.
Konta was the world number 146 in June 2015, but she believes a Grand Slam title and further progress is possible.
"The belief has been there since I was a little girl," she said.
"I'd like to be the best player in the world but there's a lot of work to be done between now and then.
