Second-ranked Novak Djokovic of Serbia split with American coach Todd Martin on Monday, but says he will continue to work with Marian Vajda.

The 22-year-old Djokovic started working with Martin last August but said that working with two coaches had become too complicated.

“I’m not working with Todd Martin anymore,” said Djokovic, who is playing at the Monte Carlo Masters. “I’m full-time with Marian again and hopefully we can have a lot of success.”

Djokovic, the 2008 Australian Open champion, said that the two coaching styles were not compatible.

“We tried to work with two coaches, and Todd is a fantastic person who has so much experience and he shared everything with me,” Djokovic said. “But it just did not work out in the end and we separated with no hard feelings.”

He added that there were difficulties when Martin worked on his serve.

“He tried to change that, but it was all to complicated in the end and now I’m back to the old one,” Djokovic said.
