That isn't an upgrade over Canavaro and doesn't solve any problems. Good, we are taking a young CB, but we still need LB and the one we loose is better than all the rest we have. The worst about it all is him, being the best we have, still isn't a good option.
And I hope we are not going to use Bonucci as a RB? So whom? Zebina or Grygera would be starting next year? I think it counts as an odd year, therefore its Zebina's turn to be the starter and Grygera the 'immedium impact substitution'. He is in and we concede in 5 minutes, regardless of the opposition?
Somehow it doesn't feel Marotta will do 4 first team players in 4 weeks, all deals being close to a steal in terms of transfer fees.
So 21st of June our defence is:
? - Chiellini(if Madrid does ot knock heavily on that door)-?Bonucci?-Zebina
A good thing about all transfers these years is that we could probably watch DP being a starter in 2056 and we'd still feel like he is the best player on the pitch.
