Austrian teenager Lilli Tagger has leant heavily on the knowledge of a former champion she calls “the Queen of clay” throughout her run to the Roland Garros girls' singles final.

The 17-year-old, who defeated No.1 seed Emerson Jones 6-4 7-6 (5) in a semi-final on Friday, is working with 2010 Roland Garros champion Francesca Schiavone.

The first Austrian to reach the girls’ final at Roland Garros, Tagger said the Italian champion is assisting her with some of the finer details in tennis that translate to success on the court.

“Of course, on clay court she is the queen,” Tagger said on Friday.

“For the game, she can teach me a lot on the clay court, but I think it's not just about the game, it's more about the mental part where she was also very strong. She's teaching me a lot.”

In an interview with the WTA website earlier this week, Schiavone reflected on her triumph in Paris in 2010 but said she had a new goal to aspire to with Tagger.

“I’m coaching a very good junior player (named) Lilli Tagger. My goal is to watch from the outside my player win a Grand Slam,” she said.

The spotlight has been on Tagger at Roland Garros, in part due to the brilliant run French sensation Lois Boisson enjoyed in the women’s singles when reaching the semi-finals.

Tagger defeated Boisson to win her first ITF W35 senior title in Spain in March and told the ITF earlier this week she was delighted given it was clear Boisson was a strong player.

On Friday she reiterated the straight sets victory over the new French No. 1 had fortified her belief that she was capable of achieving greater things in her tennis at all levels.

As an example, her win over Jones was her first in three outings against the Australian, securing her a place in the girls’ singles final against Great Britain's Hannah Klugman.

“Of course, for the clay court season, (beating Boisson) gave me a lot of confidence, because I feel very good when I’m playing on the clay court,” Tagger said.

“Especially so because she’s a very strong player and, I think, in the juniors there’s no one like her, so I have the feeling that if I can beat her, I can beat the rest of them.

“I think in the Australian Open (against Jones), I didn't believe in myself that I could win it. But today I just entered the match and just went for my goal. I didn't think for one second to lose the match. I just went for it.”

While the unseeded Tagger is yet to drop a set at Roland Garros, Klugman demonstrated tremendous fighting spirit to become the first English player since Michelle Tyler, who won the girls' singles title here in 1976, to reach the final.

The No. 8 seed clinched her third three set triumph in five matches this week when overcoming a slow start against Rositsa Dencheva, a member of the ITF-operated Grand Slam Player Development Programme Touring Team, 1-6 6-3 6-3 in 1hr 39min.

“I’m just a bit shocked, to be honest. I wasn’t playing my best and I found it tough to get myself into the match,” she said.

“I felt like as soon as I did that, I was in a good space and I thought I would do well if I got into the match.

“I think I’ve been mentally very good this week. I think I’m staying calm in big moments and also just trying to take it in.”

Klugman was all smiles after her triumph and said her team, which includes long-standing coach Ben Haran and strength and conditioning coach Jez Green, have stressed the importance of embracing competing in prestigious events.

“These moments don’t happen a lot, so trying to enjoy it is a big part,” she said. “My coach and physio (Will Herbert) are basically saying to ‘Go out there and enjoy it’, because you never know if you’ll be in the spot again.”

The girls' doubles final will feature Alena and Jana Kovackova, who won an all-sisters semi-final against Annika and Kristina Penickova 4-6 7-5 10-3. They will play German combination Sonja Zhenikhova and Eva Bennemann after the pair defeated Tagger and Mia Pohankova 7-5 7-6 (5) later on Friday.
