Rafael Nadal insists he has immense respect for Nick Kyrgios's talent, despite his criticism of the Australian last week in Acapulco.
But the Spaniard also said that players need to show 'good values'.
Kyrgios survived three match points to beat Nadal in the quarter-finals but afterwards Nadal claimed that Kyrgios "lacked respect".
"I never said nothing too negative about Nick, even if he took it more personally," said the Spaniard.
"But there's other stuff in my opinion he can do better."
The 17-time Grand Slam winner added that his comments had nothing to do Kyrgios hitting an underarm serve during the match, which he said did not make him feel disrespected.
