Rafael Nadal says he does not think his uncle and former coach Toni could ever wish him to lose - despite now guiding his next opponent at the French Open.
Nadal, 35, plays Canadian ninth seed Felix Auger-Aliassime in the fourth round at Roland Garros on Sunday at around 15:00 BST.
Auger-Aliassime says he thinks Toni Nadal will watch the Court Philippe Chatrier match from a "neutral" place.
"I want the best for him and he wants the best for me," said Rafael Nadal.
"I don't think he will be able to want me to lose, without a doubt.
