There was a time when Caroline Wozniacki was getting criticized for not winning the Grand Slam events. But at least she was winning other events.

Reuters reported Tuesday that Wozniacki is going back to her father Piotr as her coach as she suffered another early exit in 2014, this time at the BNP Paribas Open in Indian Wells, Calif., to Jelena Jankovic 6-3, 6-1.

Wozniacki, fiancée of professional golfer Rory McIlroy, has a 6-4 record this season and is trying to find a coach after firing Thomas Hogstedt in January after just a three-month partnership. Hogstedt was Maria Sharapova's coach until last May and joined with Wozniacki in October.

Wozniacki became the world's No. 1 tennis player in 2010 after reaching the U.S. Open final in 2009 before losing to Kim Clijsters. Wozniacki is still winless in Grand Slam events.

Reuters reported that she asked Piotr to step aside in 2011 as she began a search for a coach that would help her recapture the No. 1 ranking and win major tournaments.

She hired Ricardo Sanchez, according to tennis.si.com, but that relationship ended after just two months in February of 2012. Wozniacki then hired Thomas Johannson later that summer, but the two parted ways after just four months.

She has been working with former Li Na coach Michael Mortensen since splitting from Hogstedt but will get her father involved again.

"It sounds like a cliche, but after trying various coaches I've found what works best. When my father is there it is safe and fun," she told Tuesday's edition of the Politiken newspaper, Reuters reported.

"I won't go out and get a new coach in my team at any price. One thing I've learned is that a coach shouldn't just be good professionally. Because we are so close when we travel, we have to click personally."

Other than McIlroy, who is in his own slump, Wozniacki doesn't appear to be clicking with anyone.

And the current No. 12 player in the world admitted that she has to recapture her motivation to become No. 1, which may be why she can't keep a coach.

"I'm in a situation where I do not have to think about money, everything I achieve from now on is just a plus. It's about enjoying it, you only live once."

"When you start playing, everything is new and it's easy to find the motivation. Now, it's about finding the desire to play - and if you don't have that, you may as well give up."
