Yes so far he scored a good number of goals, but I think even a third or more than that was with penalties. Not that they don't count, but they are more of a present to pimp the statistics. Before he arrived someone else was taking the penalties with great success and that privilege was now taken away from that guy and given to Ronaldo. That is not to disrespect his performance in the SPL, but it is still important to kind of reasonably classify his overall performance in a league that is far below the level he used to play in the Premier League for Manchester United (first stay there) and Real Madrid with the biggest rivalry the soccer world has ever seen between him and Messi.
There are many differences if it is associated with his appearance at Real Madrid or at Manchester United, at Real Madrid many players are able to provide assists to Ronaldo in scoring goals and they have a class of players who are far different from al-Nassr. And vice versa when he was at Manchester United even though his appearance was much decreased. The media is too crowded talking about competition between Ronaldo and Messi so that despite appearing extraordinary at an age that is no longer young, it is still associated with competition with Messi.
Talking about the level of appearance is undeniably at this time Ronaldo's appearance is far more decreased than when he was still in Real Madrid and even the second season at Manchester United was far worse, so he got doubts from the Old Trafford public and had conflict with Erik Ten Hak which eventually decided to move to al-Nassr.
Found the numbers, he scored 14 goals (5 penalties) in 16 games. I have no problem with penalties as they are part of the game, but usually the ratio is a bit different than this. Scoring more than a third of the goals from penalties is a bit off the charts I am used to.
Next season we might be able to see the extent of Ronaldo's ability in scoring goals and I think even though his appearance has declined but the instinct scoring his goal is still not bad.
