Well Dybala seems to play very comfortably as CF, both players don’t play in that position.
Zaniolo started as trequartista, lost his position to Pellegrini, who simply did better there. Zaniolo did great as RW tho. He has the characteristics to play as a trequartista, CM or RW.
Kulusevski’s favorite position is trequartista, but currently is doing great at RW, but has been used in the primavera as AM, RW and CM.
Both are great talents, and it’s understandable that we want them at Juve. In the perfect world we buy Zaniolo and one of them will play as a CM. Personally I think it will be Kulu.
