If he is smart, he is going the Haaland-way and chooses Dortmund or even Leipzig as the next step in his career. He is German too, so Bundesliga seems like the next natural step for him to develop further. Dortmund is well-known for developing young players and is one of the best intermediaries between smaller clubs and big top-clubs. Moving right away to a big top-club is always a risk and can hurt your development. Making one step after the other is the safer way and after two years you can move to that club as a star rather than a talent two years earlier.
