I know a lot of people talk about how players get fed and there is some truth to that, but thinking rationally about it makes me conclude that I would also feed the best player on the pitch if the situation allows it. The best aren't the best because the get fed, but they get fed because they are the best.
I will admit though that there are some players who aren't really the best but are still able to score more in a good team than in a bad team. No doubt that that is also happening. But whether you are outstanding or not is also an important question because you might have players around you that prefer to score themselves if they have the ability to do so.
Lewandowski also left out some chances so far for Barcelona that he didn't leave out during the excellent years he had in Bayern. But he is still scoring very well this season. As you said if you scored that many goals at some point you can only "decline". It is like Ronaldo and Messi when they scored 48 and 50 goals, respectively. Your next season can only get worse
Dude, I literally made a specific difference that I commented on "decline" regarding goals, not decline in general.
"Any club would feed him" is ignorant of the fact that you need good feeders. He had a great midfield at Dortmund and the best feeder in the world in City (Kevin de Bruyne) and even then, like now if teams discover how to keep the feeders quiet like you can see in past few games, then the goals do not come.
You want an example check out Ronaldo at Al Nassr. Or even at United when the feeders had bad form.
Send Haaland to let us say Jablonec or Lincoln Red Imps (this is Europa not even Conference) and see how well clubs can feed him.
But definitely, we talk about "decline" in different context. Goals can only decline after breaking records
