Quite a boast from the Norwegian international. It's however very possible if he remains consistent has that's what helped the Portuguese achieves such heights of success.
Besides those record would be shattered someday. With haaland towing similar path in terms of goals, I believe he has a good shot considering drive and hunger for goals.
He might also have to move to a better club if he intends to do that has achieving that in borrusia Dortmund might be quite difficult due the chances the team has to move into the latter stages of the competition.
