That's obvious Juve needs another forward to add more depth on their ST position. The only problem is how can they find a buyer for Vlahovic? Not many teams are interesting in acquire a player with more than 400k euro weekly salary. Unless Vlahovic can cut his salary, believe me, none will be singning him.
Juventus has actually offered Vlahovic to United, but they rejected it. United has already acquired the player they want. Now it seems that the only possibility of buying Vlahovic is Milan. So far, Milan is the club that has been most reported in connection with Vlahovic. There may also be options for player exchanges or other agreements that can be reached, including regarding the player's salary.
