Around the match
“We want to get better... and some things just take time. I'm focusing on the process and I keep getting better. So I'm not that focused on the results or ranking or whatever.”
Kostyuk M.wtatennis.com ↗“I'm just a regular person. Maybe a couple of people might recognize me, but I'm always in different places where I feel pretty safe and nothing's going to happen. That's something I enjoy. I've always been someone who's enjoyed alone time.”
