It's set to be a family affair in the Wimbledon women's final after sisters Serena and Venus Williams beat their Russian rivals in the semi-finals.
Venus took just 51 minutes to thrash world number one Dinara Safina 6-1 6-0.
But Serena had a real battle on her hands, fighting back from a set down and a match point against her to beat Elena Dementieva 6-7(4-7) 7-5 8-6.
Saturday's final will be the fourth time Venus and Serena have fought it out on court for the Wimbledon title.
While Venus was on court for less than an hour for her semi-final clash, Serena's match was more of a marathon.
The three-set thriller lasted two hours and 48 minutes, making it the longest women's semi-final in recent Wimbledon history.
