Age have nothing to do with Ronaldo , he is still very active . The reason why maybe much clubs are not interested in buying him is because of the high amount of money to sign in him. This season Ronaldo have not played football in a full match compare to last season that is why he has not done much.
Ronaldo said he was going to retire at the age of 40 that was from his past interview with Piers Morgan. He is the most ambitious footballer ever in history of football. He has said he will love to play with his son in professional football. And also, he has a lot of records to protect due to the activeness of Lionel Messi. He thinks he still has a lot of years left in professional football. I do not see him going to Saudi Arabia. And I am very sure he will sign for a top team in Europe. Possibly, Napoli.
Over the past few years, Cristiano Ronaldo has excelled as a player and done wonderful work. He has a lot of football history, and it would be difficult for a young, up-and-coming star to overtake him. But given his age, he is now too short to play for a major team, which explains why he doesn't get much playing time at Manchester United.I see him joining Saudi Arabia because of the money and nothing much. He will definitely join one of the club in Saudi Arabia speculation is going on with him join Al nassr in January.
