Ivanovic dropped to No. 64 in the world, with another first-round loss at Wimbledon, before she shot back to rank 17 this year when she won tournaments in Austria and Bali.
"I think it's confidence, and it's a strange thing because once you lose it you feel like it's very hard to get it back," Ivanovic said yesterday, according to the Australian newspaper.
“That's what I was lacking a little bit so to have that back is great," she added. "I want to get back to Top-10 [next year] and hopefully win another slam."
The 23-year-old Serbian now has Antonio van Grichen as her new coach.
Ivanovic's first goal is to win the Hopman Cup mixed-teams event in Perth, partnering with Novak Djokovic.
The Serbians are seeded as No. 1 in the Hyundai Hopman Cup XXIII and will be up against Kazakhstan's Andrey Golubev and Yaroslava Shvedova this Sunday.
