His stats may look impressive, but he didn’t play that well in this supposed best seasons in the PL history. He relied on stat padding 9 penalty goals (his personal record). Else he’s right in the mix with Cunha scoring 19 goals without a penalty.
You can’t be real. You’re comparing a young player with a lit of development to do (even when he had already been among world best player level), to a player in his thirties. Ronaldo scored in his first goal of the season in the fifth game (against Sporting Lisbon in CL), and scored his first PL goal of the season in the fifth PL game. Why did you count the game where he got suspended?

And scoring is not everything. Ronaldo was the spark of the team during his teen and twenties. Salah has been carried by the team, so he can score goals. Liverpool now bought quite a proven PL goal scorer and a very good prospect in Ekitike. They may be able to do without Salah because outside of goals, Salah hasn’t been that good stretching back to last season and beyond.
