Love Tifo's statistical breakdowns, here he's described as a "driving midfielder", strong, technical(in defence and attack), involved all over the pitch, comparative to Pogba's Juventus days when they were getting the best out of him. The thing I take away from that is why are United even in for him when they already have Pogba? I've not looked up any stats but it seems to me Pogba's form and effectiveness has declined drastically since his switch back to Trafford... I think Savic would be much better off at City, at 23y.o(birthday today?) he's not the complete midfielder yet and needs a coach who can take him there, in the PL that's Pep, maybe Klopp(he seems more focused on getting the best out of attackers than midfielders though) but I doubt Liverpool will be paying those prices.
I suppose he's just a very good midfielder with a bright future(top 5 midfielder possibly?) so you get them in when you can. It also helps if you can get away with consistently spending £90m+ on single transfer fees while your nearest neighbour takes all the flack for rising market prices, when they have yet to break the £60m mark... and you don't have to worry about criticism of your ever rising squad cost and wage costs because all the focus is on them.
I would normally say £90m is too much but given his age and potential, the Italian tax and so on, someone is going to buy him in the summer and that's what it will take. I wouldn't want that to be PL rival if he makes good on that potential. Also a future midfield with KDB/Gundo, B Silva/Foden and Savic/Fred gives us lots of options and tactical flexibly for years to come.
I hope we are in for this one, as other's have said though he's strongly linked with the rags and they get a free pass when it comes to transfer fees and wages. Weigl is 22y.o and supremely talented in his own right, if we can prize him away from Dortmund I'd be happy with that too. That's beauty of having Pep he'll improve them, teach them the basics of the system but he'll also adjust the tactics for the players if they offer something unique which most of the names we are linked to have, whereas Jose will sacrifice parts of a players game to fit his strict system IMO.
