While Dybala has the ability to play CF, he has not really played often there in his career, even pre-Juve. He's more of an support striker/false 9, then he is a number 9. He should be played closer to goal... the problem is finding a formation that would work with him playing up front and still get the best out of our other top players like Ronaldo, Costa, Berna, Mandzu. I'd really rather not see a 3-5-2
4-3-1-2 with Bernadeschi behind Dybala and Ronaldo would be interesting imo. Could easily be morphed into 4-3-3 or 4-2-3-1 or 4-4-2 with a single sub too, bringing Costa on.
