We won't get a better fullback for that amount.
He might be the best available option, but for 25M a fullback should be a proven player, not a 1-2 good seasons for Torino player. Real paid 5M more for Danilo that played for a much stronger team and even has CL experience. And Real is clearly years ahead of Juve in financial aspect so they can take higher risks with transfers.
Barcelona opted for Vidal who also played for a stronger team and got him for 15M I think.
And last, someone posted that Torino want 20 million so even they are not crazy enough to ask for 25 eventhough Bayern shits money.
If 25M is the price I would rather not make any fullback purchases. Licht and Evra arent taht bad at the moment. 20 million with part of that being in player exchange is max sensible price imo.
And sorry for any typos, my phone died and I am using brothers iphone and its dwarf keyboard.
