Man, if this is true Juve really aren't messing around. They're either 1) desperate to get rid of Dybala, 2) desperate to sign Lukaku, or 3) both.
It's hard to see the logic behind what they're doing - surely if FFP is the issue given all their free transfers' wages, you sell Dybala instead of swapping him for a player with higher wages that will potentially struggle in Sarri's preferred possession system? - but given their transfer success over the past decade, it'll be very interesting to see how this summer affects their fortunes. De Ligt at a price lower than Maguire, and Rabiot and Ramsey on free transfers (albeit with massive wages) is great business on the face of it, after all.
If Sarri really has no say in transfers (as reports suggest), I'd be fascinated to hear his honest thoughts on the matter. Not that he'll ever give them if they're any bit negative with regards to the swap.
