But after racking up her fourth in this tournament, she now finds herself facing Romanian second seed Simona Halep for a place in the semi-finals.
Virginia Wade was the last British woman to see out the full fortnight and lift the Rosewater Dish at the conclusion, 40 years ago.
Konta can also draw on sporting pedigree in her family, with one of her grandfathers having played football for Hungary during the 1950s. "I have a very high-maintenance team".
"But it is a massive compliment to me".
"I'm playing pretty solid. I'm really looking forward to playing someone who's playing such great tennis".
French ace Bartoli, 32, said: "I love the way Johanna competes on the court, I love the way she is so stable mentally, she is really very consistent in her level of play".
British star Konta and Romanian World No 2 Halep clash in what promises to be a heated affair with so much at stake for both players.
The trailblazing world No7's quest to become the tournament's first female British victor for 40 years - Virginia Wade was crowned champion in 1977 - was handed further momentum by the demise of a number of top seeds. Even though she has had her battles, she is someone you don't want to bet against. With a victory over Konta in the quarterfinals, Halep will likely become the world No. 1 after Germany's Angelique Kerber was defeated by Garbine Muguruza of Spain in the Round of 16 on Monday.
Konta is now a perennial WTA Tour finalist and after sealing the most prestigious title of her career in Miami, she will set her sights on continuing her rapid progress with more success.
Born to Hungarian parents in Australia before moving to Eastbourne, England in 2005 when she was 14, Konta has admitted she "didn't have many friends" when she was younger because of her commitment to tennis.
Clearly laying down her bid for an appearance in any future celebrity version of Great British Bake Off, Konta said: "If I've got time, it will be a chocolate chip and banana muffin".
Johanna Konta has reiterated that she relishes being involved in tough contests on the biggest stages.
Stocked with players new and old, the world No. 2 and the world No. 87, multi-Grand Slam champions, and those with everything to prove, the 2017 Wimbledon women's quarterfinals are delightfully uncertain. "We have to relish it". If she gets the No. 1 ranking, then she might join Wozniacki, Jankovic, and Safina as No. 1s not to have won a Grand Slam. No player inspires complete trust, which is why the women's tournament is so unpredictable. "You have to put Jo in the mix", she said.
The British No1 recovered her composure for the tie-break, which she won 7-3.
"She has the pressure and the expectation, but the most important thing is that she can just play her game as good as she can".
Konta had the momentum but Garcia is too good a player simply to be overwhelmed.
Now 23 and the 21st seed here, she has not yet delivered on Murray's predictions but gave Konta a headache, setting up three break points as the Briton served for the opening set.
