On December 20, the two-time Wimbledon champion Petra Kvitova said she is “fortunate to be alive” after being injured in a potentially career-threatening knife attack at her home. Kvitova, 26, underewent surgery for severe lacerations to all four fingers on her left hand — her playing hand. The incident, described as a burglary, happened in Prostejov, Czech Republic.

Kvitova is ranked 11th in the world and has won a career total of 19 titles, including Grand Slam victories at Wimbledon in 2011 and 2014.

It is understood she allowed someone posing as a utilities man access to her apartment and while defending herself in a struggle, suffered the injuries to her hand. The intruder is believed to have then run away and is being sought by police.

Kvitova said: “Thank you for all your heart-warming messages. As you may have already heard, today I was attacked in my apartment by an individual with a knife. In my attempt to defend myself, I was badly injured on my left hand.

“I am shaken, but fortunate to be alive. The injury is severe and I will need to see specialists, but if you know anything about me I am strong and I will fight this. Thank you all again for your love and support and now I would appreciate some privacy while I focus on my recovery.”
