Johanna Konta has targeted the world No 1 spot after winning the Miami Open on Saturday.
Konta defeated Denmark's Caroline Wozniacki 6-4 6-3 to claim the biggest title of her career to date.
The 25-year-old will rise four places to seventh in the WTA world rankings when they are announced on Monday but Konta is aiming to go right to the top.
"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.
"Everybody's journey is different. I needed a little more time and a little more experience to accumulate the knowledge that I have and re-use it in my matches.
"I play smart tennis and calmer tennis, I think. It just took time. On paper it looks like a quick turnaround but it's been a long time coming."
