If that run was a dream come true, this Paris fortnight is divine intervention. Guided by the spirit of her former coach Jana Novotna - the 1998 Wimbledon champion who coached her from 2014 to 2017 - Krejcikova is bidding to become the first player to win the singles and doubles titles in Paris since Mary Pierce swept both trophies in 2000.
She will play the doubles final on Sunday, alongside her partner Katerina Siniakova, against Bethanie Mattek-Sands and Iga Swiatek.
On Thursday, after Krejcikova saved a match point to defeat Maria Sakkari in their epic semi-final, the Czech took the mic and paid tribute to the widely-adored Novotna, who passed away after a battle with cancer at age 49 in November 2017.
“Every time before the match or after the match I just feel like she's there, she's looking after me,” she said.
With so much at stake on Saturday, between two players who have never met before, could Krejcikova’s connection to Novotna be an X-factor?
"This destiny thing, riding with Jana on her shoulder, you get inspiration and you get strength from things like that, it can be an intangible that nobody can really quantify,” Pam Shriver, a 22-time Grand Slam champion in doubles told rolandgarros.com.
