He will probably score lot of goals for City, and might generally win things with them too, but he really isn't some great talent many hyped him to be for years. I'd say he will be around Tevez level at best for them, which is still good, but nowhere near someone like Aguero.
Ok, I’ll do some numbers for you:
Haaland for Dortmund (all comps, age 19-21): 1,07 goals/90 and 1,36 goals+assists/90
Haaland in the CL (for Salzburg and Dortmund): 1,41 goals/90 and 1,60 goals+assists/90
Haaland for Norway: 1,08 goals/90 and 1,24 goals+assists/90
Cristiano for us in his golden boot and ballon d’or season (07/08, age 22-23): 0,91 goals/90 and 1,08 goals+assists/90
Prime Cristiano for Real Madrid: 1,07 goals/90 and 1,38 goals+assists/90
Cristiano in the CL: 0,79 goals/90 and 1,06 goals+assists/90
Cristiano for Portugal: 0,70 goals/90 and 0,95 goals+assists/90
Messi for Barca: 0,95 goals/90 and 1,38 goals+assists/90
Messi in the CL: 0,88 goals/90 and 1,17 goals+assists/90
Messi for Argentina: 0,58 goals/90 and 0,92 goals+assists/90
These are prime Messi and Ronaldo numbers.
Let’s compare with Tevez:
Tevez in the PL: 0,52 goals/90 and 0,76 goals+assists/90
Tevez in the CL: 0,38 goals/90 and 0,53 goals+assists/90
Tevez for Argentina: 0,27 goals/90 and 0,55 goals+assists/90
….and Aguero:
For Atletico (age 18-22): 0,52 goals/90 and 0,75 goals+assists/90
For City: 0,84 goals/90 and 1,07 goals+assists/90
In the CL: 0,71 goals/90 and 0,87 goals+assists/90
For Argentina: 0,67 goals/90 and 0,98 goals+assists/90
Is goalscoring a talent? The reason he’s hyped the way he is, is because he has been delivering goat goalscoring numbers consistantly since he turned 19 and has a unique set of skills.
As a pure goalscorer we haven’t seen anyone with similar numbers at his age since Pele. Tevez and Aguero wasn’t even remotely close to that tier. What makes you think he’ll hit Tevez level at best for City. There is absolutely nothing that suggests Haalands numbers suddenly would drop to Teves’ or even Aguero’s. That’s unfortunately wishfull thinking at best.
Messi and Cristiano pretty much produced their numbers playing 1st fiddle in stacked teams scoring 150+ goals every season (Dortmund around 100 in all comps)
As much as I want City to fail, if Haaland stays injuryfree there’s no way he scores sub 40 goals in all comps.
