Junior tennis coach Nick Bollettieri has said that Amelie Mauresmo is a "good" coach, and that Andy Murray is nearing his best form.
Murray split with former coach Ivan Lendl last year and his results have been patchy under Mauresmo, leading former Wimbledon champion Goran Ivanisevic to say that sacking Lendl was a "mistake".
However, Bollettieri has said that Murray's below-par 2014 was down to a slow recovery from back surgery rather than Mauresmo, and he is seeing signs that the Scot is back to his best.
He told reporters: "His game is based on movement and balance. He's much closer to the baseline now. You can't win from 10 feet back. The big question for me will be his second serve. Go for it. You might as well double-fault.
"He's attacking more and he's very good at the net. Nobody moves better than him. And all the propaganda about a lady coach, that's over. And I'm glad it's over because she's good."
