The unpredictability factor is what makes women's tennis an absolute joy to watch given the ever-so-competitive players in the circuit. The 2015 WTA Tour finals in Singapore has been the same this year with Petra Kvitova and Agnieszka Radwanska set to feature in the finale of the competition on Sunday.

Kvitova, who put up an enthralling performance to oust Maria Sharapova in the semi finals, will be in a confident mood ahead of her finals against Radwanska. Kvitova defeated Sharapova in straight sets, 6-3 and 7-6. If the Czech player comes up with a similar performance against her Polish opponent in the finals, she could walk away with the prestigious WTA Tour finals title.

However, it is not going to be an easy task against Radwanska, who defeated second seed Garbine Muguruza in a gruelling encounter, which went down to the wire. It was the Radwanska's character  -- as has been the case a number of times during her career -- which helped her reach the finals as she came back from one set down against Muguruza. The final score read 6-7, 6-3 and 7-5.

With such big victories under their belt, Kvitova and Radwanska are expected to give their final push in order to clinch the WTA title. The match between the two finalists is sure to amaze tennis fans all over the world with their wizardry on the court.

Kvitova, who is one of the best players in the circuit from the baseline, possesses a very powerful game, which can topple any top ranked player in the world. Sharapova was her latest victim. Will her powerful game once again help her sail through and win the competition?

Many might expect Kvitova to clinch his second WTA final, but Radwanska, who works his way though slowly and gradually, is a crafty player and can make players sweat for points. Radwanska is one player, who will return each and every ball and frustrate the opponent.

However, Radwanska needs to come up with a big service game during the finals as her opponent, Kvitova can make her pay with amazing ground strokes.

Irrespective of their performance on the court, it will also depend on how these players handle the pressure of such a finale in Singapore.
