Alexis Sanchez seems to have been negotiating with PSG already, while Neymar things have started very well. If either of them were to arrive, then Angel Di Maria would become unsustainable to PSG. L’Equipe assures that the arrival of the Chilean and Brazilian would result in the departure of the Argentine.
Additionally, France Yahoo Sports report that PSG’s management has already informed Di Maria of their intentions and will put him on the market.
