Caroline Wozniacki has played fearless tennis at this week's WTA Finals.
Wozniacki has brought the fear factor off court, too.
Watch: Wozniacki Humbles Halep
The former world No. 1 says Maria Sharapova's agent, IMG's Max Eisenbud, is scared to face her after he blasted Wozniacki and Agnieszka Radwanska for critical comments about Sharapova receiving wild cards.
"He is scared to even see me," Wozniacki told The Times when asked about Eisenbud. “I walk in the player lounge and he will literally walk the other way. I think that is embarrassing for him since he is one of the head people of IMG.”
In April, Eisenbud branded Radwanska and Wozniacki as "journeyman players" who are trying to keep his client out of events and "have no clue" about the facts of her doping case in comments to journalist Ben Rothenberg.
The WTA fined Eisenbud for his comments.
The agent apologized via email, however Wozniacki told The Times Eisenbud's apology is "useless" because he did not make it publicly after making his initial critical statement to the media.
"If he were really sorry, he'd have gone publicly to the media where he called me a journeyman and said that he'd made a mistake," Wozniacki told The Times. "So that apology is useless."
The 27-year-old Dane contends Sharapova, and other players returning from doping bans, should "start from the bottom and fight her way back."
“First of all, I think obviously she's a good draw to tennis, women's tennis in general. That's one,” Wozniacki said of Sharapova during Indian Wells. "But, two, I think it's very questionable, allowing—no matter who it is—a player that is still banned to play a tournament that week.
"I think that's—from the tournament side, I think it's disrespectful to the other players and the WTA. But, you know, it is what it is. Obviously rules are twisted and turned in favor of who wants to do what."
Wozniacki's criticism came after Dominika Cibulkova trashed the Russian as "a totally unlikeable person... arrogant, conceited and cold" in the aftermath of her doping ban.
"I feel like when a player is banned for drugs, I think that someone should start from the bottom and fight their way back, because it's different from an injury where someone is out because they had hurt themselves," Wozniacki said. "That way I feel like a player should be able to receive as many wild cards.
"But when someone has been banned for drugs and something that is performance enhancing, I think that you deserve a second chance like everybody else, people make mistakes, but I think you should fight your way back from the bottom.".
