His contributions for Al Nassr and Saudi Professional League is huge in expansion to other nations including European nations that have many fans of Cristinao Ronaldo or knew him well after about two decades of his career in some biggest leagues in Europe.
That's why they almost kneeled to CR7 to make him stay, they didn't let him go from Arabia, so they know why they do it, I'm sure another player would let him go, it doesn't matter, but CR7 brings fame, money and is bringing more interest to this league, I myself didn't follow this league before, now I follow it, in fact I used to follow the African league more because I think there is a lot of talent and I like the football they have there.
That's true because if Cristiano Ronaldo leaves Al Nassr, it won't just affect the team but the entire Saudi Pro League. the league has been around for a long time, but it wasn't well recognized until Ronaldo joined. His presence has brought attention from fans and attracted more talented players from European leagues. I'm impressed on how Saudi professional league teams are trying to make the league more competitive by signing young talented players from top European teams. Right now, it might be hard to convince these players players to join the Saudi Pro League, even with big offers, because playing in the European teams is a bigger achievement. But in the future, these players might be more willing to join the Saudi Pro League.
