Elina Svitolina says she will be extra motivated because of the war in Ukraine when she faces Belarusian Victoria Azarenka at Wimbledon on Sunday.
The Ukrainian ex-world number three plays the two-time Grand Slam champion in an eye-catching fourth-round tie.
For Svitolina, matches against players from countries backing Russia's invasion of Ukraine are "different".
"I'm playing for my country every single match that I play and this one will be even more special," she said.
"A lot of Ukrainians will be watching, will be supporting me. I will go out there and put the fighting spirit on and just really fight for every single point.
