Next year's World Cup, taking place in Canada, Mexico and the United States, would be Ronaldo's sixth and last month he claimed the tournament will be his last.
"Definitely, yes. I will be 41 years old, and I think (this) will be the moment in the big competition."
The former Real Madrid star is the all-time leading men's international goalscorer with 143 as he chases down 1000 career goals. Many have speculated about when the 40-year-old will retire and speaking to GOAL as per BetWright casino, Brown believes that he still has plenty to offer.
“If he can bring something to the squad, why not pick him? Does that mean he has to play every game? Look at the last competition, everyone was saying he shouldn’t play but he did ok. He knows the press are going to give him stick anyway as soon as he doesn’t score or give an assist. At the same time, he is still there for his younger team-mates and wants them to do well.
“In his mind he won’t be finished yet, and he can still contribute to the team. I don’t think he will retire from international football until he has retired completely. He’s still got the energy, that same belief, and can still do it. There are not many people that can say that at that level.”
Ronaldo currently plays in Saudi Arabia with Al Nassr and signed a new two-year contract with the club back in June, which will keep him there until he's turned 42 years old.
Ronaldo helped Portugal to the Euro 2016 title and will chase down the World Cup next year as he attempts to complete his trophy cabinet and cement his name in history even further.
