The British number one saw off the 2023 winner in straight sets in her second round clash on Wednesday (02.07.25) and hopes she will take the confidence from her performance into her third round match against world number one Aryna Sabalenka.
Raducanu said: "I think that was one of the best matches I've played in a long time, which I'm very proud of. At the same time, I didn't feel like I was doing anything outrageous, which gives me a lot of confidence. I think I was just doing the basics very, very well.
"Having won against Marketa, she's also a really top opponent, so that gives me confidence for my level. Of course, Aryna is number one in the world, been so dominant in the women's game as of the last few years, I know it's going to be a massive challenge.
"You can't really give 'nothing balls' to her. I'm going to have to be aggressive but pick my moments. I don't think I'm going to go out there and out-power her, like, size-wise and power-wise. I think I'm going to have to try and be creative, as well."
The former US Open champion dismissed suggestions that she was "unlucky" to be drawn against such a formidable opponent.
She said: "As to it being unlucky, you want to play the best. You are going to have to play them at some point if you want to win one of these tournaments. Even though it's early in the tournament, I'm looking forward to the opportunity.
"For the rest of the evening I'm going to enjoy that one because I think it was really special."
Raducanu claimed that there is "no pressure" on her against Sabalenka but insists that she does expect herself to perform at a high level against the three-time Grand Slam winner.
She said: "I don't think any athlete truly goes out there and doesn't expect anything of themselves.
"I have my own expectations of what I want to try to be able to do on my own side. In terms of result, I really don't. Especially today, I just want to take it in because I know how fleeting these moments are. It's just a really big, big honour and testament to the work I've done in the last few months with my team as well and the people I have around me to have this result."
