If anyone is looking for who to compare with Haaland, the person can choose Salah. Even at that Haaland needs to be as this wonder by next season before we could start such a comparison between him and Salah.
As long as the world of football is concerned, the only person worthy to be compared with Ronaldo is Messi, apart from that no more.
Those two guys are in the league of their own and are not compared outside their two.
Why comparing Haaland with Salah?
Salah has a nickname like an Egyptian Messi and it says all. You can compare Salah with Messi but not with Haaland. If you want to find a player who can compare with Haaland, you can consider Ibrahimovic, Cristiano Ronaldo or Lewandowski. They are strikers and striker is a position of Haaland in recent years.
If you need a player who is young and talented enough to compare with Haaland, you can consider Mbappe. People are discussing about another long dual race between Haaland and Mbappe like what happened with Messi and Cristiano Ronaldo in the last decade.
I do not think that it will be as talented as Ronaldo vs Messi duel, because that two had combined 100+ goal seasons for nearly a decade, that's not something you can see in anywhere else. Mbappe and Haaland are great players but I do not think that they are as good as Ronaldo and Messi was neither.
However, the difference is that Mbappe used to be a winger that turned into a striker, he was at left wing and played a lot of striker this year, I think when you consider it like that, a parallels can be made to Ronaldo, he used to be a left winger that turned into a striker as well. And they are both amazing physically, fast and powerful so they can run and go pass the defender. Haaland on the other hand is a lot similar to Ibrahimovic, maybe not as skillful but definitely much better positioning and he is "there" for cheap goals, people may dislike the goal, but being able to predict that is a huge talent.
There are so many comparisons here and there and it might be based on how anyone sees it which I respect so much, and no matter what, those players are good in their own way. Still, to be frank with what Messi has played and achieved and that of Salah, there is room for comparison, especially in the way they are calling him the Egyptian Messi, they are just qualifying him with something good, and it doesn't necessarily mean they are of the same feat, and to me, once you could be called in a name for appraisal, that technically means that the person is greater than you, that's the psychology at which I would like you to look at this.
Therefore, Messi is greater than Salah and Haaland which brought the whole argument. And in my personal assessment, Haaland and Mbappe are still very young in the world of football, it's unfair to be comparing them with those that would be difficult for their names to be forgotten in the world of football.
