I don't deny that Cristiano is a great player, has had a good impact on the SPL in general, I'm a fan of him too, but I don't think he's given what he should have given to Al-Nassr. No SPL title, no ACL Elite title.
CR7's impact on the Saudi League is huge, that cannot be denied. In fact, they begged him to re-sign with Al Nassr. I'm sure many of us here follow the Arab League just because he's there and many other famous players. If CR7 had left the Saudi League, it would be a fact that they wouldn't have paid as much attention to him as they do now.
