My prediction is that it will end like Bellingham, Haaland and several other players, Dortmund will make this player a star that many clubs are after and after that they will sell him for a profit. Edson Alvarez has indeed become one of the shining football players at Ajak and the Dortmund scout team is very good at seeing this potential.
The reason is just simple that it will be maybe end like it was with Bellingham and Haaland , because other Clubs has more Money that they can use for players.
Dortmund hasnt any rich guy behind there back and have to make there one Money from players and stuff.
But yeah i guess Edson Alvarez can bring something special to Dortmund and the whole team.
