A buoyant Petra Kvitova said she had received "the greatest Christmas present I could have wished for", as she revealed she was now able to move the fingers on her left hand again after being injured in a knife attack.

Two-time Wimbledon champion Kvitova underwent lengthy surgery on Tuesday, following a shocking incident that saw her sustain severe hand injuries when an intruder broke into her apartment.

The Czech is anticipated to be sidelined for at least six months, but has expressed optimism regarding her hopes of making a full recovery.

And Kvitova appeared remarkably positive as she addressed a news conference on her exit from hospital on Friday, smiling and laughing on a regular basis while providing an update on her condition.

Wearing a huge cast on her injured hand, Kvitova said: "I am happy to tell you that I am feeling well. The medical staff, police, my family and my team have all provided me with amazing support in this difficult situation. I want to thank each and every one of them.

"I have been overwhelmed by the flood of messages and love received from the tennis family, fans and public: thank you very much.

"I will use all my energy to focus on my recovery, and will do everything I can to return to the sport I love as soon as possible.

"Yesterday [Thursday] morning, during a session with the doctor, I was able to move the fingers on my left hand. This was the greatest Christmas present I could have wished for.

"I am now looking forward to spending time with my family and I ask for privacy and peace as I start my journey towards a return to the tennis court.

"Thank you very much and Happy Christmas."
