Back home in Germany they call Sabine Lisicki "Boom Boom Bine" because of her 120 miles-per-hour serves. Seeing her in full flow, you can see exactly why.
Rather worryingly for Lisicki though is the revolving door of coaches she's had in the past six months and they've all had to work alongside her father, Dr Richard Lisicki.
Team Lisicki decided to bring in Caroline Wozniacki's former coach Ricardo Sanchez after her Australian Open exit to the Dane in January.
However, that partnership lasted just a few months before he was replaced by Robert Orlik, who also works with compatriots Mona Barthel and Annika Beck.
But, after her third-round exit to eventual semi-finalist Sara Errani at the French Open, it's been all change once again.
And with Wimbledon fast approaching, Wim Fissette, former coach of Kim Clijsters, has started working with her.
Lisicki seems rather calm about the situation and insists it is important for Fissette to communicate well in order for things to work out.
"Yeah, it's been a couple of weeks now, so we'll see how we go from here," she said.
"What I like is that he works with my dad together so basically I have two coaches but they communicate well. In fact we all communicate well with each other."
Lisicki's last WTA Tour title came in 2011 when she won the Texas Open in Dallas, but since then she has suffered from a number of injuries which have put her career progression behind schedule.
In 2010 she missed more than half a year's tennis due to an ongoing ankle injury as well as abdominal and shoulder problems, but she put all that behind her in 2011 when she was named comeback player of the year.
This year she has suffered through illness and has had to pull out of a couple of WTA tournaments. In all, she has retired from as many as 13 matches during her career.
So many problems and she's only 23-years-old. Hard to believe isn't it? The subject is clearly a touchy one for Lisicki who was less talkative when it came to discussing her injury-hit career.
But, on a positive note, she is pleased to see a number of top quality players coming through the system in Germany.
Angelique Kerber is currently the highest ranked German female tennis player at seven in the world, while Julia Goerges, Mona Barthel and youngsters Annika Beck and Dinah Pfizenmaier are two of the brightest stars.
"Yeah, it's always nice to see players coming up through the ranks," said Lisicki.
"We have five really good players now at the top of the women's game and it's fun to see a lot of Germans coming through and having an entire group of them too."
If you do happen to be heading to SW19 this summer, then keep your eyes and ears wide open for the big-serving Lisicki because she's my outside tip for this year's title.
