If talk about when you were young like Ronaldo, when he was the same age as Haaland, he could have become topic of conversation throughout the world among football fans, Ronaldo greatness even showed new football fans or fans who started to appear to idolize him.
All of this happened because Ronaldo had become great player and when he was with Manchester United it was clear that Ronaldo had career and achievements that were much better than all the Manchester United players at that time.
Now he is playing in the SPL and has brought big changes to the SPL especially for Al Nassr, the team he plays for.
Yes, he started his professional career in Sporting but he became popular in Man United. He is getting popular in Man United after he was selected as the successor of number 7 left by David Beckham. From this, we know him as CR7, then became an idol player at Man United. He won almost all trophies with Man United, he was a really sensational player at a young age. But before he moved to SPL, he got his best era at Real Madrid. He ever joined Juventus and Man United, too. Now, in SPL, he also created another great individual record, too.
Yes, these two players are both players in the attacking line, but you can see that the difference between the two is quite significant.
Maybe those football fans who haven't seen Ronaldo development since he first joined European football team will never know all this.
Sure, they are different type of attackers.
That's why I assume they cannot be compared.
Anyway, people who don't know Ronaldo well, very possible to assume Haaland is better. Those people may just know football recently.
