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.
True, no one can deny that fact. There wouldn't be nearly as much attention paid to the SPL if Cristiano hadn't arrived. But that's not the point I want to discuss. Cristiano has had an impact on the league as a whole, but he hasn't made a significant contribution to his own club (Al-Nassr). Let me ask you, have they ever won an SPL title since Cristiano arrived at Al-Nassr? I think we all know the answer, LOL.
