Keep in mind wages are a bigger issue than transfer fees... so a good portion of the Pogba sale would be banked so we can offer top wages IF we were to bring in WC players. My sense is that Juve won't. Players like Reus, etc are out of the question due to their wage demands. Verrati and Isco too since they make bank at PSG and Madrid. Juve are likely going to target the next level down.
Juve is going to look to Atletico Madrid and Dortmund's business models... Lacazette seems the perfect target along with Aymeric Laporte of Bilbao, Moutinho of Monaco, etc.
