Well, it's not like we are getting close
This team has a lot of quality, you can't deny that. Now that some of our assets are aging (Buffon, Barzagli, Pirlo, Tévez) we must find them a replacement. Berardi is a very direct winger, who has magnificent positioning and a great finishing, he's not bad at all as an SS either, put him as a vice-Tévez in our team and when the time is right, if everything goes well, we will have a quality successor for the argentine.
I wouldn't dare to say that Ranocchia will reach a quality similar to Barzagli's, but I can see him doing great for us, specially under Conte.
Murru, Candreva and a new winger would totally add a different dimension; mostly because they are players that perform in positions where we don't count with anyone. Murru a LB, Candreva a RW/RWB/CM and the new winger. And the new striker that could be Gabbiadini, who plays as a CF/SS/RW.
They'd allow us to rotate more in the midfield, defense and attack; and would surely improve our bench. Apart from giving us the option to use a different formation like the 4-3-3 per example.
Maybe the bet for Nani can go extremly well and we'll get a close to WC winger for less than 15M, we don't know, but right now, the most important thing is to keep Pogba. Hell, we had a great match against Madrid using Marchisio as a winger, this team has quality and that's a fact.
