At least these 2 matches with wins give a little spirit and confidence to the players after having a new coach. Not too sure if Pioli needs a quick time to bring Al Nassr to a higher level but seeing his contribution makes me a little sure that Pioli is able to provide improvements. The match will start in the coming month and we can still see how much improvement the coach has given. Don't expect too much when playing against Al Hilal or just a draw is enough to give good results for Al Nassr.
The style of play in the Saudi Arabian league is not as competitive as Europe so it will be much easier for Pioli to improve the performance of his players to be better. Need to maximize some of the existing players so that he can give something much better to the team. Pioli is also experienced as a coach and I am optimistic that he can bring Al Nassr to become one of the title contenders and some of the players he has are also quite experienced.
There is still a lot of time to prepare for the match and facing Al Hilal is indeed not an easy matter because the rivalry between the two is quite big. But if Pioli can give something different then I am sure he can get three points in the match.
