Yes that's right the competition will be between the top 2 teams although Al Nasr is one point behind but I think their chances are still the same
Currently 27 points again up for grabs if one of them loses then the chance for title will be 50% anyway they can't miss a single point.
I think we all should know that Al Nassr which has Cristiano in them is clearly making a difference in this league which is low in quality compared to the other leagues where Cristiano has played so far,he choose to end his career here for a hefty reward in money and that was a nice move for him,as you cannot get 500 million Euros for 2 years when you are in the end of your career as a super star player.
Al Ittihad or any other team I doubt will have the consistency to win 9 games while I think Al Nassr can win all their games as long as they have Cristiano playing for them as this player clearly makes a huge difference in their games,a difference for the good of the team.
