If these rumors are true it would be a very good thing for Milan, not only because it would contribute a lot, the player would have a different environment and this does not hurt him, I understand that several teams want to take him and the advantage is that Paolo Maldini was a very good player and icon of Milan, if they succeed it could make a difference in Milan and the truth is that the team would need fresh legs.
I would guess that Dybala is not fully ready to be played in an EPL league. Right now he is the big player of a small club type of situation, not that Juventus is a small one but compared to UCL level teams, they are definitely not a major name. So if Dybala wants to go somewhere, chelsea, liverpool, city, real, barcelona, bayern etc etc all those big names, then he has to first prove himself to be a good player somewhere in the middle.
Well, I would say Dortmund is looking for a new forward person after Haaland left, that could happen, or maybe like Arsenal? Spurs? ATM? Those are all looking for strikers and he can jump to bigger names from those clubs.
