CAROLINE Wozniacki is set to add another big top-10 name to the women's field for the Brisbane International.

Wozniacki, the former world No. 1, is understood to have entered the season-opening tournament at the Queensland Tennis Centre from December 29-January 5.

Barring a late change of mind to play a tournament other than Brisbane, which she played last summer, Woznacki would give the event at least four top-10 women, joining world No. 1 Serena Williams, second-ranked Victoria Azarenka and fourth-ranked Maria Sharapova.

The flamboyant Dane, whose relationship with golfer Rory McIlroy has been the subject of speculation in recent weeks, will be keen for a better 2014 after winning one tournament of the 23 she entered this year to finish it ranked 10th.

Wozniacki told reporters at a golf tournament in Dubai last week that she would not be in Sydney with McIlroy when he contests the Australian Open from Thursday week.

"It's just too far to travel to Australia as I am playing in the Brisbane International and Sydney before the Australian Open, so I didn't want to have to make two journeys to Australia in such a short space of time," she said.

In a set of events which have parallels in Australian eyes with Bernard Tomic's dalliance for several months with the idea of hiring a coach to work with or above his father John, Wozniacki started with a new coach Thomas Hogstedt in October.

Wozniacki has been mostly coached by her father, Piotr, since she was a junior, although she worked briefly with two coaches, one being 2002 Australian Open winner Thomas Johansson, when her tennis results started to dip in 2012 and 2013.

"Now I'll just be dad. My mission - to leave and let Caroline and her trainer to work," Piotr told Danish reporters.

Hogstedt was sacked by Sharapova in July, having guided her quest from recover from shoulder surgery to win the 2012 French Open and recapture the No. 1 ranking. He has also coached 2011 French Open winner Li Na.

Wozniacki said at the US Open in August that she realised there would always be ups and downs in her career.

"The downs just make the ups even better. You know, you appreciate it more,'' she said.

"I know that when I put in the work, I am a player who can win a Grand Slam."

McIlroy accompanied Wozniacki to Queensland last December and she enjoyed the facilities and other attractions of Brisbane on her last visit that she stayed on a few days after her elimination to practice for the rest of the Australian circuit.

Woznaicki ended the season with the same ranking she came with to Brisbane, when she had an inauspicious start to 2-13 with a first-round loss to Russia's Ksenia Pervak, ranked No. 103.

The 23-year-old right-hander reached two finals this year, losing to Sharapova in Indian Wells, California before closing the year off with her only title in a $235,000 tournament in Luxembourg. She beat three top-10 players only in 2013, the best being a win over Azarenka in Indian Wells.
