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.
Juventus have to compete with Manchester United and Arsenal to get him and indeed Milinkovic-Savic said he want to find new challenge with moved to other clubs but so far those teams still hasn't officially bid for him however Juventus currently on midfield players crisis because after Pogba their other midfielder player Weston McKennie also got injured and he probably cannot play for one month or more so Juventus really required new players on that position and they should be bid Milinkovic-Savic immediately
