The Portugal superstar posted a picture of himself alongside his close friend Miguel Paixao on Instagram while they together stood at a clay tennis court.
Ronaldo has taken a break following Real Madrid‘s third successive Champions League triumph in Kiev, when they beat Liverpool 3-1 in the final.
Meanwhile, the forward will miss Portugal’s warm-up game against Belgium, as they prepare for the upcoming tournament.
Coach Fernando Santos too wants his star man to enjoy his rest period before getting down to business in the World Cup, where Portugal have been drawn alongside Spain, Morocco and Iran.
“Cristiano Ronaldo is on holiday,” Santos said.
“I won’t bother Cristiano by calling him, after a spell where he’s put in so much effort and is tired. I don’t have to talk with Cristiano.
“Hopefully he can have a great holiday and he can come back in good condition. That’s the important thing.”
