I can understand why he is choosing Juventus over United and seems to have come into agreement with personal terms as well but the big question now still remains if Juventus will be willing to break the bid set by Lazio for the player. Lazio director rates him as an important player and they will only let him go if someone matches the bid of 150m Euros. It will be interesting to see if they are ready to make that bid or maybe negotiate with Lazio but I doubt that Lazio will settle for much less than that.
150 million euros might be too much, but according to some rumors, Lazio president Claudio Lotito is adamant about selling Savic for just 100 million euros. this is an offer for Juventus to be able to take savic from Lazio. I think this is a fair price for such a talented player like Savic.
But Juventus also had to give up some of their players to leave because of Savic's arrival at Juventus. some of the candidates who might leave Juventus are Adrien Rabiot, Weston McKennie, and Leandro Paredes.
I think the price is just to keep other teams from wanting him because indeed he is still doing quite well at Lazio so far so it's quite natural that their boss is trying to hold back because he also knows that Juventus are a little bit in financial trouble right now.
But what I read is that Savic has agreed now, even though this is still not certain, especially since there has been no statement from the person concerned.
The team has terminated his contract and it happened even before Portugal's first match in the Mundial. Of course it was because of the interview he gave to the whole management, but he had no other choice, because the team treated him badly to put it mildly...
