It's too far-fetched to discuss, and it's unlikely that young footballers would choose the Saudi Arabian League as their league of choice. The Saudi Arabian League isn't as competitive as the top European leagues, and the competition in the Asian Champions League isn't as exciting as the European Champions League. Playing in the top European leagues remains the pinnacle of a footballer's career. Unless their goals in football have changed, and they're no longer focused on career advancement but rather on financial gain, they'll likely choose to play in the Saudi Arabian League, as Saudi clubs offer higher salaries.
Returning to CR7, he's a magnet for football fans all over the world, so wherever he goes, fans follow him. It's understandable, even though he's getting older, that many clubs are still interested in signing him, including one in the MLS.
It would indeed be a pity if a young player who has already built a career in Europe suddenly receives a big offer from an Arab club. We must see how Ronaldo achieved his current success. He worked hard for his career in Europe, and he reached the peak of his success. This does not mean that moving to Saudi Arabia is the best choice, but he has his own plans. Young players who can compete must work hard to secure a place in top European league teams in their careers, because we know that the level of competition there is very tight, which will enhance the players' abilities.
