Even though he hasn't been able to provide a trophy for Al-Nassr, Ronaldo has been successful enough to prove that he is still productive in scoring goals. In 16 matches with Al-Nassr, Ronaldo managed to become #2 as the top scorer of the clubs under Talisca. he success with 14 goals, while Talisca with 20 goals. So, it is not impossible that next season with a full playing schedule, Ronaldo can give his first trophy for Al-Nassr. So far there has been no disciplinary action reported. This means that he has no regrets about his decision to play at Al-Nassr.
I think it's very natural that Ronaldo failed to bring Al nassr to become champions in his first season with Al Nassr, because as we know he went to Al nassr to be precise in the second half of the season which made him not have much time to help the club win the title in this season. But another thing that is special is that he was able to make many big contributions to al nassr in other words he became the second top scorer on the al nassr team, which indicates that Ronaldo is still very aggressive in front of the opponent's goal.
Well next season I think Al nassr will be more difficult to provide resistance to al ittihad because Al ittihad surprisingly they managed to bring in Benzema to strengthen their squad in defending the title for next season.
