Erling Haaland can't be compared to Rasmus Hojlund, even when Haaland is at Hojlund's age he can score a lot of goals and has a good finishing. I believe that ETH is just gambling on Hojlund's transfer, because despite his young age, at least Manchester United will have a replacement for their striker. If later he will be officially introduced as a new Manchester United player, I can't wait to see how he performs in official PL matches.
No doubt! Haaland can only be compared to Mbappe and no one else. Even then it's hard, because Erling changed leagues and took no time at all to get settled in. Mbappe still has done nothing of the sort, but he had a stellar World Cup performance.
It would be exciting if Hojlund lives up to the expectation and hopefully by next year we
will compare him to Haaland. But there is also the possibility that we will compare him to Mudryk. Only time will tell.
