As the defending champion, Kuznetsova took a wildcard into the Kremlin Cup, knowing that she had to win the title to qualify for Singapore.

After a series of poor finals' results Kuznetsova ended her relationship with the Sanchez-Casal academy in 2009 and moved to Moscow on the advice of Roger Federer to start training with experienced Russian coach Olga Morozova. They ended their relationship after the BNP Paribas Open in March 2009, after which Kuznetsova was without a coach. As of May 2009 her coach was former Russian tennis player and Fed Cup coach Larisa Neiland. She was coached for a short period by Loïc Courteau after trying unsuccessfully to convince Mauresmo to coach her. Her next coach was for a short time the former Spanish tennis player Carlos Cuadrado, until he was replaced with her former coach Neiland. After the loss in the Italian Open, Kuznetsova has switched to Morozova, then to Amos Mansdorf and finally in May 2012 to Argentine Hernán Gumy, former coach of Marat Safin. She said in an interview, that she likes working with him and understands with him well.

Kuznetsova won their first three meetings, but in the four meetings that eventuated in 2008, Kuznetsova lost three of them, including in the third round of the Australian Open and in the fourth round of Wimbledon. Additionally, she also lost against her at the year-end championships later in the year, after Radwańska replaced an injured Ana Ivanovic. Kuznetsova subsequently dominated Radwańska in future meetings, winning six meetings between the pair between 2009 and 2012, including an upset victory at the 2012 French Open, until Radwańska stopped the rot at the 2014 Mutua Madrid Open, saving a match point in the process. Prior to 2014, Kuznetsova's two most recent titles came by defeating Radwańska in the championship match, first at Beijing in 2009 and then at San Diego in 2010. In 2015, Kuznetsova defeated Radwańska again in the opening match of Fed Cup tie between Russia and Poland.

She was elected in the final that year. There, she won against Mara Santangelo and Schiavone from Italy. Russia again won that year's Cup.

Belgian tennis legend Justine Henin was one of Kuznetsova's leading rivals during the middle portion of her career. Of the 19 matches that they played, Kuznetsova earned three victories, including their final one. Henin won their first meeting in the 2003 Wimbledon Quarterfinal when Kuznetsova, just 17, lost in straight sets. Kuznetsova earned her first win over the Belgian at the semifinals of the 2004 Total Qatar Open, where she went on to lose in the final to Anastasia Myskina. This result projected the Russian into the world's top 20 players for the first time. Arguably their finest match followed in the fourth round of the 2005 French Open, where Henin saved two match points en route to a three set victory. Henin went on to win the tournament, defending her title a year later by beating Kuznetsova in the 2006 final. Henin additionally defeated Kuznetsova in the finals of the 2007 US Open grand slam tournament in straight sets. Kuznetsova beat Henin for the second time in the finals of the 2007 Qatar Telecom German Open tournament in Berlin in three sets, becoming the second-to-last person to do so in 2007. The Belgian went on a seven-month, 32-match winning streak after Wimbledon, having lifted the French Open directly beforehand. Henin unexpectedly retired in 2008, but returned to the tour briefly in 2010, only to suffer an elbow tear at Wimbledon. Justine Henin made one final comeback following her injury at the 2011 Australian Open, where Kuznetsova defeated her in a dramatic match in the third round. Due to the recurring nature of her elbow injury, Henin retired immediately following her match with Kuznetsova, making the Russian the final person to play against and defeat her.

Kuznetsova made her debut in the main draw of a Grand Slam at the 2002 Australian Open, where, as a qualifier, she reached the second round before losing to 16th seed Iroda Tulyaganova. However, she previously lost in the qualifying rounds of both the 2001 French Open and 2001 Wimbledon.

At the 2006 French Open and the 2007 US Open singles tournament she was the runner-up, both times to Belgian player Justine Henin. As a result, Kuznetsova obtained a career-high No. 2 WTA ranking, holding that position for 24 weeks in 2007 and 2008. Since the 2010 season, Kuznetsova lost her top 10 position and even dropped down to a year-end ranking of 72 in 2012, until recovering in 2016, when she progressed to the top ten and reached the semifinals of the WTA Finals, her best result in that tournament to date.
