Well, we all know that Dybala wasn't a meta player on FIFA 19, the lack of stamina, 3 start week foot, combined with the fact that he was average in everything and good in nothing made his failure. But in FIFA 20 thing has changed, I liked him so much and he is so incisive that he became my favorite player so far.
No doubt the pro is his agility, how fast he can change direction and get out of tight places make a huge difference. I tested Hunter and Engine on him and I can say that Engine is better, the Agility adn pass gain compensates the speed loss and for a CAM the finishing is enough to score multiple goals. If you intend to use him as a ST, maybe hunter will fit better for you.
I think he would be the double of the price if he has a better week foot and a High work rate for atack. His physique can be a problem as well depending on your playing style.
