Plagued by injuries and a loss of form in the past two years, Nadal has risen to number one in the rankings and won his 10th French Open title and third U.S. Open this year. He lost to his great rival Roger Federer in the Australian Open final.
"Carlos has been a great support. He came with excitement and also the belief that with a few things, I could improve my results. And it has helped," Nadal told Spanish newspaper El Espanol.
"It has been a breath of fresh air, positive energy. We have changed the way we practice and for Toni it has been also good."
Nadal said Moya came on board and studied his daily practice sessions before offering specific ideas on how he could improve his game.

"When someone new arrives, it's easier to listen because it's something different. For Toni, having Carlos' reinforcement when he had to talk to me, has made everything much easier."
Toni had said earlier this year he intended to step down from his role at the end of the season and Nadal praised his efforts working with Moya and Francisco Roig.
"They have been a great team and I am very satisfied with their job, with the three of them,” he said.
Nadal will play in Beijing and Shanghai next month as he looks to secure the year-end number one ranking and winning his first ATP Finals title.
