London, June 30 Ahead of their semi-final clash, world No. 1 Dinara Safina has warned five-time Wimbledon champion Venus Williams that she is set to repeat her Rome victory.

Safina, 23, is looking to reach her first Wimbledon final and has lost twice to Williams - but won their last meeting in Rome, The Sun reports.

Safina, who saw off Germany's Sabine Lisicki 6-7 6-4 6-1 in the quarters yesterday, said: "Venus loves playing at Wimbledon but I have nothing to lose. I played her in Rome in May and beat her.

"I know her weapons but I have my own. I just want to go out and play my best. So let's see."

Despite her spot at the top of the women's game, Safina, sister of retiring men's singles player Marat Safin, has not won a Grand Slam title.

She was thrashed in the final of the Australian Open by Venus' younger sister Serena and then lost the French Open final to Svetlana Kuznetsova. (ANI)
