De Ligt is more marketable?
Have you seen what he looks like?
The Netherlands has a population of 17 million. Argentina? 45 million.
People in South America are more likely to follow a team because of Dybala than people in Europe (and outside of Holland) are likely to follow Juventus because of De Ligt.
Does De Ligt have a signature celebration?
Also, attackers and midfielders are more marketable and put people in the stands. Do you know why? Because they score goals, and that's what people want to see.
Is De Ligt more impactful? Sure, it might be that he has the same impact as Van Dijk @ Liverpool,
but that hasn't happened yet. Half a season an impact does not make.
Please stick to whatever it is you do for a living, because clearly marketing and debating are not your strong suits.
