Toni Nadal says in an interview that he does direct comments at his nephew Rafael during matches. On-court coaching is not allowed on the ATP Tour or at Grand Slams.

“I talk to Rafa during matches. I know that it’s not allowed but I think that at my age I have nothing to hide,” Toni told the Spanish journalist David Nadal.

Toni Nadal added that he sees little value in using sports psychologists, and added, “In the tennis world, those who are mentally stronger, are also technically stronger.”

Rafael Nadal, who again has been battling knee trouble, will return to the tour at the Canadian Open in Montreal during the first week of August.
