Watch: Barbora Krejcikova's emotional WTA Finals speech brings Martina Navratilova to tears

The Czech duo of Barbora Krejcikova and Katerina Siniakova secured the women's doubles title at the 2021 WTA Finals, defeating the Taiwanese-Belgian pariring of Hsieh Su-wei and Elise Mertens in the summit clash.

The final of the season-ending tournament coincided with the 32nd anniversary of the Velvet Revolution, which saw the erstwhile state of Czechoslovakia transition from a non-democratic regime into a parliamentary republic.

After the match, Krejcikova paid tribute to the "brave Czechoslovakian students and citizens" who protested the communist regime in the region. The 2021 Roland Garros singles champion said that it was because of their sacrifices that her generation could live with "freedom" in a "beautiful country".

"Today is a really special day for the Czech Republic and also our Slovak friends," Krejcikova said. "We call this day the Velvet Revolution. On November 17 1989, Czechs and Slovaks had been one nation. We had very brave Czechoslovakian students and citizens and they went outside to the streets and they had been demonstrating against the non-democratic regime we had then."

"Thanks to them and their sacrifice, my generation can live in a beautiful country back home and we can live without any restrictions and with freedom," she continued. "So everybody understands what was happening back then."

Martina Navratilova was moved to tears during the speech.

The 25-year-old also addressed a visibly emotional Martina Navratilova, who was part of the trophy presentation ceremony. Navratilova, tired of Czechoslovakia's totalitarian policies which compelled her to put her tennis career on hold and give up a large chunk of her earnings, sought asylum in the US back in 1975.

Krejcikova ended her emotional speech by expressing pride in belonging to the Czech Republic.

"We have here Martina Navratilova who was forced to emigrate from Czechoslovakia because of the regime there," Krejcikova said. "I'm really happy that regime is not there anymore and we can live in freedom."

"So just want to say that I want to thank everybody back home and I really appreciate what they did, how brave they were," she added. "They gave us the opportunity to live in freedom and I'm really proud to be from Czech Republic."
