In a 4-3-3, maybe not, especially if I have Rashford too. I'd play him up-top, dropping deeper and inter-changing passes with Martial and Rashford on the side, trying to create a fluid 3 of sorts. Or, if it's a diamond, as Ole is also prone to do, I'd play him at the tip of the diamond, behind the striker. He has a tendency to drop deep, really good link-up play, circulate possession, create chances and score decently. He actually fits an Ole striker perfectly. The problem arises when both Rashford and Dybala are in a squad, but using Rashford as a wide-forward could work. Maybe.
Regardless, Dybala is the only player of Juve that we should be interested in. Not Douglas Costa, who has been linked recently (old, inconsistent). I'd have liked Cancelo, but he is off to City (who, once again, are having an excellent summer with a replacement for Fernandinho in Rodri and Cancelo)
