As of July 4th, Caroline Wozniacki still ranked No. 1 in the world about 2,000 points ahead of world No. 2 Kim Clijsters. 

Meanwhile, Petra Kvitova of the Czech Republic, who won earlier this year at the Brisbane Open, Paris Indoors, and the Madrid Open on clay, just added her first Major title of her career by claiming Wimbledon. On Monday, Kvitova was stood at No. 7 in the world standings.

Of course, we have to understand that under the current world standings rules, the more you play, the more WTA points you earn, regardless of the category of the event you play.

Here is why Wozniacki is still the world's No. 1, while Kvitova is six spots behind the Dane:

Wozniacki has played 14 tournaments so far this year, while Kvitova has played in only 10. Wozniacki has won Dubai, Indian Wells, Charleston, Brussels and Copenhagen, while Kvitova won Brisbane, Paris Indoors, Madrid and Wimbledon.

Meanwhile, Indian Wells was the biggest tournament Wozniacki won this year and you have to wonder why she played Brussels, the week prior to Roland-Garros and Copenhagen, the week prior the Wimbledon.

Of course, some will argue that she wanted to play in front of her home crowd. But was it worth expending so much energy just one week before Wimbledon?

In a way, you have to wonder if she realised just what it would take to win a major. 

At the end of the day, such strategy is a loser.

Of course, Wozniacki won Brussels and Copehangen. However, the Dane spent all her energy winning the lower-ranked tournaments rather than focusing on Majors.

Now, the same headlines abound regarding the World No. 1 being unable to win a Grand Slam. If Wozniacki wants to be a real contender in the big four, she will have to change her attitude towards them very soon.

The current World No. 1 was a semifinalist at the Australian Open, but then lost in the third round of Roland-Garros and the last 16 of Wimbledon. She may improve her record at the upcoming US Open, as hard court is her favorite surface.

Meanwhile, Kvitova won Madrid on clay, which is as important as Indian Wells, and she won Wimbledon on grass, which is more impressive than what Wozniacki accomplished this year.

The 21-year-old clinched Wimbledon after dominating Maria Sharapova 6-3 6-4 and showed signs that we would have to count her among the elite very soon.

The new generation didn't have enough time mature while former stars retired (Kim Clijsters, Justine Henin, Martina Hingis), and when the Williams sisters weren't able to be on the Tour all season long.

What I call a big champion is a pretty rare player who wins consistently on Tour for four, five or even 10 years.

This 2011 Wimbledon winner has everything it takes to be one and should become the next boss of the women tennis.

She's mastering all the shots required by the modern game and has the perfect game to win Grand Slams, contrary to Caroline Wozniacki, who hasn't produced enough offensive weapons to win a Major.

Kvitova's weapons are obvious: a powerful, accurate and regular serve, a huge forehand, a backhand getting better and better with every passing season (it has even become another weapon), and outstanding timing which allows her to fire such heavy shots.

The lefty Czech reminds me of Lindsay Davenport, who won her first Grand Slam in Wimbledon in 1999. Of course, Kvitova still has much room to improve physically.

It's not that surprising to see Kvitova triumph considering the amount of confidence she built on different surfaces in recent months—Brisbane (hard outdoor), Paris (indoor) and Madrid (clay), against top 10 players such as Clijsters, Li Na, Sam Stosur, Victoria Azarenka and Vera Zvonareva. All of this helped her to change her status and to reinforce confidence that now will never leave her.

Last but not least, here is one of the secrets to Petra's success: she knows her own strength and abilities. Therefore, when she's feeling good, she just feels like nothing can stop her.
