Garbiñe Muguruza and Magdalena Rybarikova's head-to-head is tied at 2-2. Their first three meetings occurred in 2013. In her second career Slam main draw, a No.112-ranked Muguruza emerged on top of an epic Australian Open first round 4-6, 6-1, 14-12, before Rybarikova had her revenge on the fast indoor courts of Paris a month later 3-6, 6-1, 6-3. The Spaniard moved ahead once more at Indian Wells that year to the tune of 6-4, 6-0 - but two years later, in their only grass-court meeting before today, Rybarikova notched up an equally straightforward win in the first round of Birmingham 6-3, 6-1.

Since the quarterfinals were set, Johanna Konta has led her head-to-head against every other remaining player. She's ahead 3-2 on Venus Williams. The American toughed out their first match in a 7-5 deciding set in the 2015 Wuhan quarterfinals, but Konta reeled off their next three encounters, all on hard courts: the first round of the Australian Open in 2016, the final of Stanford in the same year (for the Brit's first WTA title) and in the semifinals of Miami this year. Williams proceeded to pull one victory back in the third round of Rome in May.

Garbiñe Muguruza has been the most efficient of the four semifinalists so far, with seven hours and six minutes of court time. Johanna Konta, with ten hours and 20 minutes, has spent the most time on court. Muguruza and Venus Williams have dropped one set each (to Angelique Kerber and Wang Qiang respectively); Magdalena Rybarikova has conceded two (to Karolina Pliskova and Petra Martic), and Johanna Konta has lost three (to Donna Vekic, Caroline Garcia and Simona Halep).

Johanna Konta is the only semifinalist who has won a title this year, having seized trophies in Sydney and Miami. Venus Williams has one runner-up place, at the Australian Open; neither Garbiñe Muguruza nor Magdalena Rybarikova have reached a final this year. This is Muguruza's fourth semifinal of 2017, following Brisbane, Rome and Birmingham; it is Rybarikova's second, after Nottingham.

Venus Williams is bidding to follow Martina Navratilova's footsteps in 1994 by reaching the Wimbledon final as a 37-year-old. Navratilova was beaten that year by Conchita Martínez - who is now coaching Garbiñe Muguruza during The Championships.

Johanna Konta is seeking to become the first British woman to make the Wimbledon final since Virginia Wade in 1977, while Magdalena Rybarikova is seeking to become the first Slovak finalist at SW19 ever (having already become the first Slovak semifinalist here). The only Slovak woman to have reached a Grand Slam final thus far is Dominika Cibulkova, at the 2014 Australian Open.

Venus Williams is 8-1 in Wimbledon semifinals, with victories over Serena Williams (2000), Lindsay Davenport (2001), Justine Henin (2002), Kim Clijsters (2003), Maria Sharapova (2005), Ana Ivanovic (2007), Elena Dementieva (2008) and Dinara Safina (2009). Her sole loss at this stage came at the hands of Angelique Kerber (2016). Garbiñe Muguruza, the only other remaining player to have reached this stage of Wimbledon, is 1-0 in SW19 semifinals, having beaten Agnieszka Radwanska in 2015.

Venus Williams and Garbiñe Muguruza are both guaranteed to return to the WTA Top 10 after Wimbledon. Williams was last ranked in the Top 10 in April, while Muguruza dropped out of it after failing to defend her Roland Garros title last month. A title for either would return them to the Top 5 - where Johanna Konta is also guaranteed to debut on Monday. Meanwhile, Magdalena Rybarikova will soar back into the Top 40, and could reach the Top 20 with a title.

Venus Williams has not beaten a Top 10 player at Wimbledon since her win over No.1 Dinara Safina in the 2009 semifinals; Johanna Konta's quarterfinal victory over Simona Halep was her first Top 10 win at this tournament. Garbiñe Muguruza and Magdalena Rybarikova have both doubled their number of Top 10 wins at Wimbledon during this fortnight, from two to four and one to two respectively.

Johanna Konta has a reputation as a relatively late bloomer as a Top 10 player - but as Naaman Zhou reveals for The Guardian, there were early signs of self-discipline and hard work in her Sydney childhood.
