well, that pretty much is true for all players, to be fair.
look at the argentinian and the portuguese, for instance - the former needed gifted penalties to score and lift the world cup trophy, no impact in paris either, living off the past glory in barcelona; the latter was shrunk down to real size once the rest of the team's purpose was no longer assisting him to reach personal records, causing him to disappear to western asia and milk the sheikhs for as much money as possible.
haaland was a prolific goal scorer for dortmund too, and they arguably had a weaker squad.
