Petra Kvitova has said that her game is in great shape heading into the French Open.

The 22-year-old, who captured her first Grand Slam title at Wimbledon, believes that she is a threat on any surface after racking up six titles last year.

Kvitova has had a disappointing year so far but revealed that she is in confident mood as the second Major of the year approaches.

"I think from last year that I can play on all surfaces and I won in Madrid on the clay, Wimbledon and I won on hard court as well, so I think that I have a game to play very well on different surfaces," the Czech told Laureus.com.

The world number four believes that Victoria Azarenka and Maria Sharapova will pose the biggest threat in Paris.

"I think [Azarenka] started very well this season and she played very well," added Kvitova. "She is more consistent than before and Maria Sharapova is playing very well. She won some tournaments again and I think that those two players will be in the top for a long time."

Kvitova lost to Sharapova in the semi-final of the Australian Open.
