The 36-year-old has been part and parcel of the Portuguese national team for close to two decades, having made his debut for the Selecao in August 2003.
Ronaldo has since gone on to become one of the greatest footballers of all-time with five-Ballon d’ors to his name.
The former Real Madrid and Juventus forward is now international football’s greatest goalscorer, having found the net an incredible 115 times in 182 games.
It has been suggested that Ronaldo could retire from international football after next year’s FIFA World Cup in Qatar to prolong his club career but the Manchester United forward says that is not entirely the case.
"Why? I think it's not my time yet," Ronaldo told Sky Sports News when asked if he was considering international retirement. "It's not what people want, it's what I want.
"It's when I feel that I'm not capable to run, to dribble, to shoot, if the power is gone ... but I still have that stuff so I want to continue because I'm still motivated. It's the main word - [motivated] to do my stuff, to make people happy and my family happy and the fans and myself. I want to put the level even higher.
"You speak about Portugal but in the Champions League I have the most goals, the most wins, assists … everything. But I want to carry on. I like to play football. I feel good to make people happy."
Ronaldo led Portugal to glory in EURO 2016 and the inaugural edition of the UEFA Nations League in 2019.
