‘Nadal will be back to his best in 2016’

Rafael Nadal's coach, his uncle Toni, believes the 14-time grand slam champion will be back to his best in 2016, following a disappointing run on the ATP Tour this year.

Toni Nadal believes his 29-year-old charge is looking as comfortable and confident on court as ever, as he prepares for his 11th Australian Open campaign.

"I couldn't do this work if I thought that he couldn't win more grand slams," the coach told ESPN.

"He can win the Australian Open in January, and he can win Wimbledon, too. The last few years, Rafael arrives at Wimbledon and he loses early, and very fast. In Roland Garros, for sure, Rafael can win. In tennis, you need the confidence to do things. It's impossible to do anything without confidence. 

"You can't win any good tournaments if you think you cannot and you don't believe."

Toni also said his nephew was distracted by various things throughout 2015, which ultimately led to a drop in form.

"Rafael is much more comfortable on the court now," he said.

"In this moment, he thinks about what he needs to do, and then when he gets on the court that is what he does. For many months this year, he was thinking about what he wanted to do, about this or that, but then when he came on the court, he couldn't do it. Now he can do it, and that's good. It gives him the possibility to play well. 

"I think Rafael during the last two months has played so much better than earlier in the season.

"(Nadal needs to do) what he tries to do every day on court, which is to play more aggressively from the baseline, and to go into the net when he can, and to improve his serve."
