That's because he is/was supposedly an Inter fan. I am not convinced he has the right attitude for Juve, would he be willing to work his way to the first team or would he want a first team role immediately, especially after he refused Juve last summer because he wants to play regularly. He is very highly rated and he could start for most top-table Serie A clubs , if he thinks he needs to play regularly to improve further then wouldn't he prefer some other club? Also this is going to be an expensive buy, €25m+ worth of player(s), and Juve already got atleast two youths in Morata, Dybala for next season and possibly also Coman.
