Sergey Milinkovic-Savic is a rumoured player to sign for Juventus these days. Pogba has got injured so they need to sign a new midfielder. Milinkovic-Savic would be one of the best alternatives for Pogba and he might even perform better than Pogba when he is back from his injury. Lazio's demand would be really high from them but I don't think that they would care about that much. Their finance is very well and they can afford him easily if they want to.
