Li Na, a story of believing

When Li Na vowed to win another major a fortnight ago, many doubted if the Chinese star could deliver it.

At 30-plus and late career though, Li lived up to her word by winning the season's very first Grand Slam at Melbourne Park.

The fourth seed's 7-6 (3), 6-0 win over Dominika Cibulkova crowned her as the Australian Open champion on her third attempt after the 2011 and 2013 finals, adding to the French Open title she won three years ago.

Li silenced those who suggested that her best was behind her, and with this victory, Li has proven she isn't a fluke.

China rejoiced over Li's latest triumph, with Web users and media praising the landmark achievement from the country's tennis trailblazer.

However, the journey from Roland Garros to Melbourne Park is not just about name and fame. It's more about failure, desperation, self-doubt and thoughts of retirement.

In the past 31 months, Li has experienced a roller-coaster life and she had spent more than a whole year rebuilding faith in her game and career.

Li had struggled to adjust to her new status as a major champion after the 2011 French Open while distractions of sponsors and media also drove her off her game. For almost a year, she had been without a title and even found it hard to reach a final.

With expectations sky-high, Li saw her form nose-diving and she fled the press conference in tears after a fourth-round Australian Open defeat to Kim Clijsters in 2012.

"I must handle the pressure of expectations from more than a billion people back home, and it's not easy," Li explained in her autobiography Du Zi Shang Chang, which literally means "Playing Myself".

The downslide stopped when Li hired Carlos Rodriguez, the former mentor of multiple Grand Slam champion Justine Henin, in mid-2012 following conflicts with her husband-cum-coach Jiang Shan.

It proved a highly effective move as Rodriguez became, as Li put it, "a savior of both my career and marriage".

"Being coach and husband is very tough to find the balance, so I need a new coach," Li said after crashing out of the first round of the London Olympics in 2012.

Encouraged by Rodriguez, Li is no longer afraid of making changes. She has been working on her net play and altering grip on serve and backhand.

She has better managed her schedule and reserved some of her best tennis for when it counted.

But Rodriguez's influence is not limited to technique as the Argentine has instilled in the player a self-belief that had been lacking.

"I'm very proud of her but at the same time there's still big work to do because she still doesn't realize how good she is," said Rodriguez earlier last season.

"It's also up to her desire that she is gonna have, go back to work and improve different things on court, but the most difficult work is inside."

In the first tournament after joining forces with him (despite communicating with him only electronically), Li reached the final in Montreal. The next week she won an event in Cincinnati, joined midweek by the Argentine.
