Martina Navratilova is ready to join the growing group of former star players turning to coaching, while Andy Murray's former coach Ivan Lendl says he would be selective about working with another player.

Navratilova, speaking while in Singapore to promote the WTA Championships, would like to use her tactical and strategic knowledge to get a player to the top of the game.

"There's no substitute for that one-on-one, getting into the nitty-gritty of the game," she said. "And you can only really do that with a top player, when you're just searching for that little edge. That sliced backhand or the dropped volley that you may only use once or twice a match but may mean the difference between winning or losing."

However, she is still waiting to be approached by the right player. "I love getting into those details of the sport. I'm sure it'll happen," she said.

Meanwhile, Lendl told the press in Flushing Meadows that while he could no longer commit the time Murray required, he would consider coaching another player if it would "fit right."

“It wouldn’t have worked if Andy had called me two years earlier, or if he had called me two years later," said Lendl. "And it has to be someone I feel I can offer something to. If it was John Isner, for example, I am not going to be able to tell him how to hit serves."
