Cavaday came close to beating Martina Hingis in 2007
Kent's Naomi Cavaday is full of confidence ahead of the biggest match of her life against defending Wimbledon champion Venus Williams.
The 19-year-old from Chislehurst, who is ranked 197 in the world, faces the seventh seed on Centre Court in the first round on Tuesday.
"I'm really confident. I feel I've got some things in my game that can really upset her," she told BBC Radio Kent.
"To get the chance to play someone like Venus is just amazing."
"I'm just so excited," she added.
I felt a lot more comfortable now I've had a look around
"I think I can cause her trouble as I play slightly differently from a lot of girls out there."
It will be the first time Cavaday has played on Centre Court at SW19 but she is not fazed.
"It feels totally different to what I'd expect walking onto Centre. It's a lot more intimate than I thought it would be. I thought it would be a lot bigger.
"I felt a lot more comfortable now I've had a look around."
It is the third outing at the event for the teenager - who had two match points against former champion Martina Hingis in her opening match in 2007 - before losing in three sets.
She was also beaten in the first round in 2006 by Ai Sugiyama.
Williams has won the women's event four times - in 2000, 2001, 2005 and 2007.
