Dinara Safina has warned of a possible WTA Tour boycott by leading players over changes to the schedule.
She added: "No one seems to understand which tournaments you can play and which you can't."
"They said the leading players would have to play in designated tournaments while lower-ranked players would be able to enter any event they like," said Safina after losing to fellow Russian Vera Zvonareva at the Kremlin Cup in Moscow on Saturday.
"There's no logic in that at all. What if all the top players choose to enter the same tournament? What will the WTA do then? We want to know. There are a lot of grey areas."
Former US Open champion and world number two, Svetlana Kuznetsova, agreed with her compatriot.
"I was told only two players from the top 10 could enter a smaller tournament like the Kremlin Cup next year," said the current world number seven.
"What if Jelena Jankovic and Serena or Venus (Williams) want to play here?
"Then all the top Russian players, and there are five of us in the top 10, will not be able to play in their home tournament. That's nonsense."
This does seem unfair
- what if top players are coming back from injury and wish to play in the smaller tournaments?
- this must be a change to 'year on year' ranking points!
- do you think a 'girlcott' will take place?
- what are the full new changes? (unsure myself) and what do you think of them?
