Serena Williams feels that she has a lot of improving to do despite winning the Rogers Cup without dropping a set.
Williams has always been a perfectionist and despite dismantling Sorana Cirstea 6-2, 6-0 in the Toronto final with apparent ease, she told the media that she isn't entirely happy with the quality of her tennis at the moment.
"For me, it's always about constantly improving and never saying I did great and I can be satisfied," she said. "For me, it's like I did great but what can I do better? What can I improve on? That's what I always strive for."
She has already won eight titles so far in 2013, equaling the record she set during the 2002 season when she was totally dominant. And with four months of the season still to go, she looks set to add many more to her tally. Only Agnieszka Radwanska came close to touching her in Toronto.
Before heading to Canada, Williams won the Swedish Open on the clay of Bastad but while she won the title without dropping a set she said that she was bitterly disappointed with the quality of her tennis.
"I took some time off [after Bastad] and I was really disappointed in how I played the last month," she revealed. "Even though I won Sweden, I was not happy with the way I played. So I went home and was working with my dad a lot and just going back to the basics. I didn't show it so much in this tournament. Hopefully I can continue to bring that game out."
This is her 17th season as a professional player and no one would argue that she does not have anything left to prove but she admits she still gets nervous ahead of matches.
"I had butterflies today," she said. "I will have butterflies at the Open. Hopefully I will have seven singles matches at the Open. I think it almost is exciting to have butterflies, because it means that you care about it so much and you still get nervous. I think when the day comes and I'm not nervous and don't have butterflies, then I need to start rethinking what I'm doing."
