VICTORIA AZARENKA knows she needs to start learning from her mistakes if she is deliver on her undoubted potential.

Azarenka is a two-time Grand Slam winner, both titles coming in Australia, but there is no doubt that given her undoubted talent she should have achieved more.

She has reached five other slam semi-finals, including two at Wimbledon, but too often she has been found wanting when serious questions have been asked.

And she gave a frank assessment of her tennis following a 6-3, 3-6, 7-5 defeat to unseeded Serbian Bojana Jovanovski - her second straight second round defeat at SW19.

“I have to be realistic,” said Azarenka, who only returned to action at Eastbourne last week, having played just one match since January.

“I cannot sit here and say it’s all great, because there’s no moving forward from there. I’m going to be hard on myself just because I want to be better.

“It’s my consistency, it’s not enough. There are a lot of things that still has to be tuned and has to be practiced. It basically goes down to back to work.

“I don’t want to take credit away from her or anything but I always look at what I did. I don’t really care what the person done in front of me. Look at the statistics, I didn’t convert 16 break points - that’s just ridiculous.

“I’m going to have to just work harder. It’s as simple as that. It’s just work and play and practice, all of it together. Nothing else, just focus on tennis.”

Former champion Petra Kvitova sent out a clear message of intent with a 6-2, 6-0 demolition of Germany’s Mona Barthel.

Kvitova has been a picture of consistency at the All England Club, reaching the quarter-finals for the past four years and winning the title three years ago. She plays five-time winner Venus Williams next and admits self-belief is brimming.

And confidence is certainly key to a player who can look unbeatable one day and distinctly ordinary the next.

She clearly enjoys being on grass, her court coverage was excellent, she won 10 from 11 at the net and her timing was spot-on.

“I felt pretty good on the court,” she said.

“Grass is my favourite surface and there are a lot of nice memories for me here from 2011. That gives me a lot of confidence. To win a grand slam, especially here at Wimbledon, is great and when I am here it’s nice memories every time.

“But Venus is a great champion and she likes to play on the grass as well but she’ll be a tough opponent for me.”

Meanwhile, Australian Open champion and second seed Li Na was far from fluid but still overcame world number 38 Yvonne Meusburger from Austria 6-2, 6-2 and fourth seed Agnieszka Radwanska was another straight-sets winner.
