According to the Brazilian Goal journalist, we are interested in Alves, Sandro and Bonucci, and would offer over €100m for the last two combined.
They also say Juve are looking at Roma LB Emerson as a replacement for €25m.
I have a weird feeling that won't be near enough for Sandro and Bonucci. Chiellini and Barzagli are 32 and 36, respectively. With Bonucci being 30, I feel like they'd need to hold onto Bonucci to transition to a defense without those two. If they lose Bonucci, they'd need to go after a new pair of CBs and a backup. Losing Sandro on top of that doesn't bode well with Alves being 34. I feel like they'd require alot more to replace their two established talents and make moves to replenish the entire defense going forward. For now, I'd say just go for Sandro and look for other options at CB.
