There are 10 more games left, if they win as much as they can, there is still time to recover from this and there is just one point difference, so a tie from ittihad means that they could end up being better in the long run with a win at the same week and they will get back the lead.
It's very difficult for any team to beat Al Ittihad this season, because they have strong defense. Maybe Al Nassr should wait for another team to prevent Al Ittihad from scoring and force them into a draw, like what Al Raed recently did. From other side, both teams still have a match against Al Hilal, who are the only team that could affect the current standings, in my opinion. However, the excitement may last until the last rounds of the league, just like the previous season, when Al Ittihad lost a match and drew in another, resulting in Al Hilal winning the title.
So far, Al Ittihad has a great chance of winning a trophy this season. they only suffered one defeat in 20 matches this season, 14 wins, 5 draws. Al Ittihad's only defeat was when playing against Al Hilal. well, if Al Ittihad is able to topple Al Hilal in the match later, they are even closer to the pro saudi league trophy. but if the opposite happens, then Al Nassr has the opportunity to shift the top of the pro saudi league standings and has the potential to win a trophy this season.
but what is certain, the pace of the two teams that are currently competing in the race for the trophy this season. looks like it's not going to run smoothly. because, the two teams still have tough matches in the remaining 10 matches in the future. if Al Ittihad is able to be consistent, then their chances will be difficult to be overtaken by their competitors. and vice versa, Al Nassr must win the remaining 10 matches until the end of this season, including overthrowing their toughest rivals, namely Al Hilal and Al Shabab. if, Ronaldo and his friends succeed in maintaining their consistency. So, they deserve the pro saudi league trophy.
But, yes, there is still plenty of time for both coaches to prepare their respective teams for high performance.
