Former women's world number one Caroline Wozniacki has parted company with her Spanish coach Ricardo Sanchez after only two months of collaboration, the Ekstra Bladet daily reported on Wednesday.
The decision, announced by Wozniacki's father and confirmed by Sanchez, comes after her elimination in the quarter-finals at the Australian Open, which saw her fall to fourth place in the WTA ranking.
In December, Sanchez broke off his partnership with Serbian former world number one Jelena Jankovic to work with Wozniacki, who had dropped her father, Piotr, as her coach in August.
"We decided to evaluate the collaboration and we agreed to bring it to an end," Piotr Wozniacki told Ekstra Bladet.
Sanchez told the newspaper that the decision was due to his differences with Wozniacki's father, who had been the Dane's only previous coach.
"I have great respect for Piotr, who has never played tennis himself, and for the work he has done," said Sanchez.
"But he has his way of doing things, and I have mine."
Sanchez added that "Caroline was just confused" by having two coaches "who wanted different things".
Despite the failure of her partnership with Sanchez, Caroline Wozniacki has not ruled out taking on a new coach, according to her father.
"If Caroline finds a coach that she thinks might suit her, we'll take him," he said.
