Since his move to Manchester City, Haalaand was immediately able to adapt well to the Manchester City game and even in the first and second season he ended the season with the championship and also the status as top scorer, Haaland sharpness in scoring goals is no longer in doubt, but as you said, he is still still has weaknesses at the moment, Haaland has accuracy and speed in executing opportunities to become goals and he even knows enough where to stand when his teammate gives an accurate pass in a match, but like you say, Haaland is often invisible when he has to face big team and it is even difficult to escape when they are closely guarded by a tough defender.
I would say different that Manchester City had to change their tactics to help Haaland. It's quite not fair to say Haaland depends completely on Manchester City tactics change and his team mates to play well. He tried and adapted somewhat and we have to consider that Manchester City had demand to change themselves so they saw something helpful in Haaland before purchasing him from Dortmund.
Haaland played like a beast in his first season for Manchester City and in Premier League debut season but in a second season, he struggled to score goals when clubs, coaches and players in Premier League understood his playing style more and found ways to reduce his danger. Fortunately, Haaland did not join Euro 2024 and he can use summer time to watch videos, think deeply of ways to change and play better next season.
