"She has managed to raise her game to the same level as the best," says Ferro ahead of Boisson's quarterfinal at Roland-Garros

This Wednesday, Loïs Boisson can make an even bigger impression at Roland-Garros. Benefiting from a wildcard for the 2025 edition, the 22-year-old Frenchwoman has defied expectations by reaching the quarterfinals of a Major tournament in her very first appearance.

After victories over Elise Mertens, Anhelina Kalinina, and Elsa Jacquemot, the Dijon native pulled off a massive upset in the previous round by eliminating world No. 3 Jessica Pegula on Court Philippe-Chatrier (3-6, 6-4, 6-4).

For a spot in the semifinals, she will have to overcome another tough challenge in the form of Mirra Andreeva, the world No. 6 and last year's semifinalist at Porte d'Auteuil.

Speaking to the French Tennis Federation's media, Fiona Ferro analyzed the keys to the match and believes Loïs Boisson can truly trouble the 18-year-old Russian player.

"She's one of the few girls I couldn't manage to take more than 3 or 4 games per set against in practice. Her heavy serve and forehand kept me out of reach. I couldn’t take control of the game.

So, I’m not surprised to see her competing with the top players at this Roland-Garros. That’s her greatest strength: finding her opponent’s weaknesses and always being able to change tactics.

Back then, there was a gap between her level in matches and in practice. But she’s become more consistent. She’s found a structure that’s helped her maintain stability. What impresses me most is that she manages to keep that consistency match after match.

She’s not very expressive, she doesn’t talk for hours, but she’s incredibly disciplined. She spends an hour warming up and two hours stretching," said Ferro, who had trained with Boisson in a French Tennis Federation training group before facing her in a tournament in 2023.

"If she can’t let her breathe… I feel like the only players Andreeva struggles against are those who overpower her with speed and power.

Otherwise, she always manages to outmaneuver her opponent and turn situations around. I think Loïs has all the tools to keep Andreeva at bay. Now, she just has to do it for an entire match without any ups and downs.

Through hard work, she’s managed to raise her game to the same level as the best. And honestly, I think she’s playing incredibly. Pegula really played a great match.

When you can beat that kind of player, there’s no reason you can’t do it again," concluded the world No. 444 in the hours leading up to her compatriot’s match.
