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
Savic would definitely be a great improvement for Juventus but we all know why that won't work right now. They are not going to actually get him and spend that much extra money on something like this when they are staring down the barrel, that would be causing them to overpay and nobody really wants that. I hope that they could find a way to get it done, but I have a feeling they won't actually get it done in time.
I am sensing that the best thing to do right now would be using the players they already have instead of letting others to blackmail them to buying someone they know they would have to overpay for just because of this Pogba situation they are in right now.
