Maria Sharapova needs to end her 16-match losing streak against Serena Williams if she is to reach the women’s singles final at Wimbledon.
The Russian, 28, was victorious over Williams in the final at SW19 in 2004, but aside from one other victory that year, she has not managed to beat the world number one since.
In fact, Sharapova has taken just one set off Williams in the last seven years and in their last meeting on grass, at the London 2012 Olympics, she managed to win just a solitary game.
Despite her dismal record, the five-time Grand Slam champion is confident that she can win to reach what would be a first Wimbledon final since 2011.
“I think it’s always a new match,” the world number four said.
“I haven’t had great success against her. I would love to change that around. That’s how I look at it.
“There are definitely no secrets between each other’s games, but it will be an incredible moment for me to step out on Centre Court against her again.
“There’s no easy road to victory. You’re going to have your bumps. That’s the way I see it.”
Sharapova came though a tough quarter-final against powerful American Coco Vandeweghe.
She now faces another in Williams, who battled back from a set down to Victoria Azarenka, to reach the last four at Wimbledon for a ninth time.
Chasing a 21st Grand Slam, which would put her just one behind Steffi Graf’s all-time Open era record, Williams has lost just one match so far in 2015.
