Petra Kvitova says she’s “working really hard” on her recovery from a knife attack that took place in December. The two-time Wimbledon champion and former No.2 posted an update on her Instagram page on Tuesday.

“Hi guys! I wanted to say hello since time is flying by – three whole months already since the attack – and let you know that I’m working really hard on my recovery. I still can’t tell you when I will be back, but I can tell you that tennis is a huge motivation for me and I realised while I’ve been away how much I like challenges!

“My perspective on life has changed a lot and I am doing everything to give myself a second chance to be back on the court. I thank you for staying with me through this and I hope to see you all soon, love Petra.”

On December 20th of last year, Kvitova was attacked in her home in Prostejov by a knife-wielding assailant, suffering deep cuts to four fingers on her left hand that required immediately surgery.

The tennis community has rallied around the 26-year-old in her absence, most notably at the BNP Paribas Open last week, where fans turned a large support sign into a de facto get well card.
