The Frenchwoman will play in her second SW19 final this afternoon, having lost to Venus Williams in straight sets in 2007.
The 28-year-old told BBC Sport: "The last time I was so young. I was always the underdog coming out on the court and this time it was totally the opposite.
"I think I've been able to deal with the pressure really well and keep improving throughout the Championships and keep playing better."
