Yes, it is very surprising with the achievements achieved by Al Nassr to date because his dream was to become SPL champion but until now he has not been able to achieve it. But yes, it is true that one of the problems that Al Nassr has is the lack of strong defense which of course means that Al Nassr is still unable to recover.
but if you think about it, Al Nassr has struggled to the maximum up to now, but yes, I agree with your opinion. In this case, Pioli must be given time to overcome all this because it is definitely not easy to build a team to be even better, especially Other teams who are currently building their respective squads will definitely make the competition even tighter and of course in this case Pioli's abilities will really be tested.
Al Nassr, which is currently in 4th place, is indeed an achievement that does not meet the expectations of Al Nassr fans, but honestly I hope that from now on Al Nassr can rise and its performance will be better and improve. Yes, considering that up to now Al Nassr has only competed 13 times in the SPL, of course there is still plenty of time for Pioli to be able to improve Al Nassr. and I'm sure Pioli will be able to carry out a better strategy and I'm sure Pioli will learn from the Al Nassr matches that have passed.
