Ronaldo's first club in Europe was Manchester United. He probably wanted to finish his career with Manchester United. Joining Manchester United in the second round was the biggest mistake for Ronaldo as we saw him never get the respect he deserved and he was sidelined and other players were allowed to play. When he was regularly disappointing for Manchester United, we didn't imagine that he could come to Saudi Arabia as his next destination because we didn't know much about this league before. He introduced us to a new league by signing Al Nasser and since his departure the number of European players going to the Saudi League has increased.
Al Nasser and Ronaldo have mutually benefited from signing each other so I think Al Nasser will definitely let him finish his career at the club with respect.
Now we are having extension for him with most chances his career will be ended after the end of the 2026 as he is also having his eyes fixed on becoming first player in soccer history with 1000 goals in career which could be huge achievement for him and Al Nassr with his performance in last season we can expect another good season for him.
