I think in order to get James, Dybala must be sold. So that in itself makes it unlikely. But if we were to sell Dybala, the price would be very high. We could probably buy James+another player. If it were let's say Mbappe & James in and Dybala out, I'd obviously be happy with it. But realistically, I'm skeptical on a James deal. Agnelli has said he really likes him though.
But we should be actively looking at finding long term replacements for C. Ronaldo & Mandzukic in particular. Mbappe is a replacement for Ronaldo, but esp if we stay with Allegri, we'll need to find another target man.
