Al Hilal keeps up their winning ways in every match. Al Hilal only scored two goals in the first half of their game against Al Ettifaq, and they controlled the game from beginning to the end. According to H2H Al Ettifaq haven't won in the previous ten meetings against Al Hilal, they will either lose or draw. While leading the league table with 59 points, Al Hilal has managed to hold onto their position, as they are still ahead of Al Nassr by 7 points. Al Hilal is the favorite team to win the league title this season because of their strong play from the beginning of the season.
