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. Because if Al Nasr doesn't immediately improve the squad it currently has, I'm sure Al Nasr will only be able to finish in 3rd or 4th position in the Saudi Arabian league. The problem is that if, for example, Al Nasr does not overhaul its players on a large scale, Pioli as the coach will not be able to develop his strategy to the maximum.
Al Nassr attack is always good and competitive but their defense and midfield always lack of creativity which hurt them badly through now changes are happening to they are working on few players for having them which will surely increase their depth in defense while midfield is also looking for better players.
Stefano Pioli surely understand this situation as if they want to win trophies and having better results surely they needed to be had balanced side now competitiveness is increasing, and they are going for more challenges which need better preparation from them as well.
In this season, now difference of 9 points looking big but if they will prepare for next season things could be better and well balances which will help them for having top spot in league table with trophies as well.
