Indeed. The next season will be interesting since both Benzema and Ronaldo are in different clubs. So, they will be rivals, which one to be the best striker in the next season. However, if there is no significant change both in Al Nassr and Al Ittihad, I think Benzema will have a bigger chance to be the top scorer. Al Ittihad looks stronger, especially since they have Benzema for the next season. SPL atmosphere may be as well as the top league in Europe for the next season. 
Don't get your hopes up that the atmosphere in the SPL will be like Europe's top league. In the past, we had hoped that CSL would become one of the big leagues in Asia and the atmosphere would be like Europe's top leagues, but what now? CSL is just like an amateur league. As additional information, it's not just Benzema who will play for Al-Ittihad, because there are rumors that Kante will also be going to Al-Ittihad soon, all of this is getting more interesting to look forward to.
