The top four women in this year's Wimbledon will take Center Court on Thursday to play for a shot at the final.

No. 13 Agnieszka Radwanska and No. 20 Garbine Muguruza will go head to head, followed by the 20th time No. 1 Serena Williams and No. 4 Maria Sharapova will face each other.

Williams vs. Sharapova

This is the matchup that has stood the test of the last decade. Sharapova, who will be elevated to the No. 2 spot after Wimbledon, has not managed to get a win against Williams in more than a decade, her last win being the same year as her 2004 Wimbledon title as a 17-year-old stunner. Since then, Williams has dominated their matchup, steamrolling the Russian by winning 16 consecutive times.

"Definitely no secrets between each other's games," Sharapova told Telegraph UK. "But, I mean, look, I haven't played Serena here in 11 years," said Sharapova, although she did face Williams in the 2010 Wimbledon. "That would be an incredible moment for me to step out on Centre Court against her again."

Serena's winning streak against the Russian is testament to her desire to continue dominating the Siberian Siren.

"I love playing Maria," Serena said, as quoted by USA Today. "I think she brings out the best in me. I think I bring out the best in her. I thought we had a wonderful final in Australia. It was very entertaining. She played really well. For me, I don't feel like I have any pressure going into this match."

Williams almost lost to Heather Watson in the third round and has brought her A game in the succeeding matches. She defeated her sister Venus in straight sets in the fourth round and displayed her dominance in the best match of the tournament so far - Williams vs. Azarenka 3-6, 6-2, 6-3, propelling the World's No. 1 to the match against Sharapova.

After forcing Serena to three sets in their last three matches, Azarenka was asked for her advice to Sharapova. She answered: "If I had one, I would have used it today, trust me."

Radwanska vs. Muguruza

Radwanska and Muguruza are two surprise semifinalists who came out of the bottom bracket. Radwanska, a 2012 finalist, excels in the grass court. She has made the semis at least in three of the last four Wimbledons.

On the other hand, Muguruza, the Spanish-Venezuelan 21-year-old, never had playing on grass courts as her strong suit. She never had a strong showing in Wimbledon before this year. Making it to her first Slam semifinal, she says she's as surprised as anyone.

"I'm very happy to be to semifinals because I lost two times quarterfinals," Muguruza said in the Wimbledon press conference, talking about her two quarterfinal matches at the French Open. "I'm surprised that my first semifinals is on grass. But I think I'm playing really good. I think the surface helps me."

She beat No. 5 Caroline Wozniacki in straight sets, No. 10 Angelique Kerber in three sets, and No. 15 Timea Bacsinszky in two sets.

Muguruza won the last two hard court matches against Radwanska in the Sydney Women's Singles and the Australian Open.
