Cristiano Ronaldo's future with Portugal in question after star player leaves camp. Here's how we got here

Cristiano Ronaldo walked out on Portugal's training camp in Copenhagen on Wednesday, giving no indication on if or when he might return to the national team.

The move came days after Ronaldo watched from the bench as Portugal defeated Norway 2-1, with his replacement, Gonçalo Ramos, scoring the game-winning goal. And it came hours after Portugal coach Jorge Jesus announced that Ronaldo would not start the next day's game against Denmark.

Ronaldo has more international goals (146), victories (141) and appearances (234) than any other men's soccer player. He said during this summer's World Cup, his sixth, that it would be his last .

But Ronaldo also has indicated he wants to keep playing in pursuit of his 1,000th career goal. He currently stands at 979 goals, accounting for his international play as well as professionally with Manchester United, Real Madrid, Juventus and, currently, Al-Nassr.
