At the same time, this young player will be able to stay with Bayern Munich for a long time
Yes, that is right. If Bayern Munich really decide in favour of de ligt they will enjoy him for many years. After all he is only 22 years old.
It shows in general that Bayern Munich is setting itself up better and better for next season and that they will finish the season as German champions again. They should not worry about that. We can also see that their focus is clearly on the Champions League.
