Al Nassr indeed controlled the game, but the defense built by Damac was strong enough that Al Nassr could not penetrate the defense in 90 minutes of the match. Maybe one of the factors why AL Nassr had difficulty attacking was because the players on the front line who were usually their main players were not deployed from the start. Cristiano Ronaldo, Sadio Mane came off the bench in the second half. This may be one of the reasons why they had difficulty penetrating Damac's defense, especially in the first half. However, they were also able to secure victory even though they had to wait until the last minute.
This was a good competitive match but the problem is in my opinion Al Nassr should have been able to score a lot more goals than only one. They should have been able to score at least three goals with all the chances that they had. And one time the ball came off the crossbar which should definitely have been a goal because he was right in front of the goal. And the cross from Ronaldo was also perfect. Anyway at the end of the day Al Nassr got the wind and that's what matters. I think we can expect Al Nassr to finish on the second position in this season because they are not sliding down to the third because they have a good point advantage over the team that is on the third position. And I don't believe they are also going to be able to win the league title because Al Hilal has created a big difference of points with them.
As for the title, I see that is impossible now, they are too far from Al Hilal who can comfortably be at the top of the standings. However, this is not entirely their fault, because Al Hilal themselves have played extraordinary this season. It is very difficult for other teams to beat them and it can be seen from their record that they have never been defeated. Even when Al Nassr faced them, in fact it was Al Nassr who lost. In fact, one opportunity to get closer to Al Hilal is to beat them when AL Nassr meets Al Hilal.
Maybe next season they can try again, and I hope they can be even better, especially in defense, because their defense line also has many shortcomings this season.
