Kvitova can dominate for years to come
Petra Kvitova can blow anyone else away with her powerful game when she is at her best, and the Czech has a very special and successful career ahead of her.
I would certainly back Kvitova to usurp Caroline Wozniacki at the top of the world rankings, and she could well be very dominant for years to come.
The 21-year-old is very unlikely to ever win the French Open because of her game, but I could see her winning the other three Grand Slams time and time again.
Obviously, if Serena Williams and, to a lesser extent, Kim Clijsters return to their best next season that could really shake up things at the top.
But Kvitova has the power game required to dominate the rest of the field, and I did not see her coming this year.
The impact the Czech made at Wimbledon was truly remarkable, and it shocked everyone in the game.
The major concern most people had for her was whether she possessed a plan B when things were not going her way, but she has begun to address that.
Kvitova is superb when she has the opportunity to go for her shots, but she has often lacked flexibility if a change of approach is required.
However, we saw a dramatic improvement in that regard at the WTA Championships in Istanbul, and she showed everyone that she can come through testing matches with guile and intelligence.
Very little of her play was spectacular, and in the final she was not on top form -- yet she remained brutally efficient and ruthless in getting the job done.
Sometimes the 21-year-old's timing goes slightly, but she is not a nervy type of player like so many of her rivals on the WTA Tour are. She always holds herself together.
Kvitova has such a big game that she can blow most players off the court, and her strength of character and composure is also hugely important.
People have already started talking about Kvitova now going on to emulate Martina Navratilova, and while it's a tremendously exciting idea it is way too early to say that she is that kind of once-in-a-generation player.
Of course, it is conceivable that the Czech could emulate her compatriot, but it's far too early to speculate in the long-term.
Kvitova did get lured into the limelight back home following her Wimbledon exploits, but that was a quantum leap in terms of her career.
I cannot see the Czech going off the rails again, and she could very realistically win a couple of Slams every year.
Women's tennis does tend to be a great deal more volatile than men's tennis, but someone like Kvitova could well clean up if her rivals continue to stumble and falter.
Wozniacki, on the other hand, needs to fundamentally change her game if she is to ever become a great player.
The Dane needs to improve her second serve considerably and add many more weapons to her groundstrokes if she is to win Grand Slams.
Of course, Wozniacki will always win tournaments on the WTA circuit, but she lacks the cutting edge and the inspiration on the big stage to really dominate opponents such as Serena, Kvitova and Clijsters.
There is no doubt that women's tennis is currently at a very intriguing crossroads, and Kvitova has to be the favourite to emerge from it as the dominant force in the game.
