Winning is mainstay for most of these players, they're only here to win games and lift trophies based on their topnotch profile in football. Al Nassr can actually survive without the heavy presence of keyplayers but in either ways, their presence is very compulsory and becomes valuable when the appropriate spots is hits. Cristiano Ronaldo and Sadio Mané have contributed heavily to the growth of Al Nassr all these years playing for the club. These are the best representatives of the Knights of Najd, they're outstanding in performance and will always come out ranking top base on their impressive stats. Al Nassr are lucky enough to have these players in their club. Only Ronaldo who's always ambitious, he nets goals and everyone knows how his goals tally have upgraded the level competitive performance of the club.
True. All players must expect to win in every match. However, it is not easy for Al Nassr, they still missed points in some matches. Although Al Nassr has some top players in the world, they still can't perform consistently and win the SPL trophy. Sure, they are lucky to have Mane and Ronaldo in the attacking line. But it is not enough if Al Nassr can't improve their defense line. Ronaldo and Mane may score many goals, but they still can be defeated if Al Nassr is conceded many goals as well.
Yes, in essence the balance of players that Al currently has is not good. Because if we look at the front line, Al Nasr currently has quite good players like Ronaldo and Mane. But in the midfield and at the back, Al Nasr really doesn't have players they can rely on. For this reason, this season Al Nasr was unable to get maximum results in every match. This was the main trigger because the defense and midfield were not good. So Al Nasr really has to carry out changes on a fairly large scale to make his team even better.
You're right. Al Nassr has a strong attacking line but they have bad defense line. In the defense line, they have not much strong players. Especially for the left and right backs. The only strong defender is Laporte, he can't cover all the defense line if Al Nassr relies on him only. There should be strong players for right and left backs, too. Since each Saudi club only can have limited European players, I think it is better for Al Nassr to find our strong left and right backs from local players.
Regarding the midfield line, I think they have 2 good players (Brozovic and Otavio). Sure, they need 1 strong player again, it is a strong defensive midfielder. I heard a rumor that Al Nassr will sign Casemiro. Casemiro is a perfect player for the position. I hope it is not only a rumor but Casemiro really comes to Al Nassr squad.
