40 years old Cristiano Ronaldo is trying to have few historic achievements so Pioli is giving him right things as he not brings him for the Kings Cup game now against Al Wehda he was on pitch for the 90 minutes which is good workout by this legendary player even not able to score field goal but still having name in scorers list through penalty goal and increase his tally of goals for having first player in soccer history with 1000 goals.
Ronaldo is still 39 years old, he isn't 40 yet. 
In the match against Al Wehda, Ronaldo scored a single goal from penalty kick. It is good for Ronaldo, he expects to score 1000 goals. If he continues to play above 40 years old, I think it is not impossible to reach a record of 1000 goals.
We have third win for the Al Nassr and Pioli in this game with their performance and defense both are having good improvement now they need consistency which keep them for the title race and having good chance of winning trophies in this season after having terrible last season.
You're right. Pioli has won 3 matches in 3 matches. He did something impressive since he worked with Al Nassr team. I believe he has the capability to improve the performance of Al Nassr because he has a lot of experience managing some big teams such as AC Milan, Inter Milan, Lazio, Bologna, and Fiorentina. But to win SPL trophy, it is not something easy because Al Nassr has a very strong competitor (Al Hilal).Cristiano Ronaldo was also in a very good form last season as he scored the most number of goals in the Saudi Pro League but it didn't stop his team from losing the league title to Al Hilal.
He was the top scorer last season. It was the most productive season for Ronaldo. But this season looks like very difficult to be the top scorer since Mitrović and Benzema become very productive. Meanwhile Ronaldo is decreasing its productivity in scoring goals.
