Agnieszka Radwanska would like to see another change in the WTA schedule, saying the WTA Elite Trophy should not be mandatory for players who qualify.

The 26-year-old, who earlier this week called for the season to be reduced to nine months, said the required tournament further increased the length of the season. The new WTA Elite Trophy in Zhuhai, a 10-player round-robin event, features players who did not qualify for the WTA Finals in Singapore.

"I think, for example, the smaller Masters in, or I don't know how you can call it, in Zhuhai, I think that's something that shouldn't be really mandatory for the players," Radwanska said. "I think it has to be your choice, especially that it's after Singapore. So it makes your season much longer. Two weeks does a lot for us."

The event is meant to host players ranked from No. 9 through No. 19, as well as one wildcard entry. Players who qualify are required to compete, though two or more players who are alternates for Singapore do not have to participate.

Radwanska, currently ranked No. 8, also criticized the amount of points given at the event, suggesting it would have a significant effect on season-end rankings, particularly around the edges of the Top 10.

''I think there's also too much points there. I mean, [you're] ending after Singapore, for example, No. 9. Then someone's getting 700 points. Suddenly from No. 9, you're No. 12. You thought you finish No. 10," she said. "I think that's couple things about that tournament that should really change."
