Milinkovic-Savic is going to cost more than 70m (rumours that Lazio have already rejected 70m offer, probably from Juve), Weigl's price would be exorbitant.
Juve would never pay £70m for a midfielder, let alone DM. Higuain was a one off purchase for them and its hard to argue his goals weren't worth it.
Milinkovic-Savic will go for around £50-60m. Weigl £60-70m. We are taking about DM. Few clubs pay those prices for attackers players let alone DMs. Barca, Real, Chelsea are set in that position. PSG is not buying at that price, they have bigger issues to worry about like keeper. Rags have just bought Matic so it rules them out. Milan no chance, Inter no chance. Maybe I'm even exaggerating the prices.
