Inter will lose three defenders in summer according to the Gazzetta dello sport. Walter Samuel and Cristian Chivu due to expiring contracts. Ranocchia is expected to leave for another club since Mazzarri is having other solutions in mind at the moment. Then it remains to see what happens with Andreolli and Rolando. This is also the reason Inter is signing a defender like Vidic for free.

Is that vidic better than samuel
Chivu and Samuel are leaving for sure. Keep Rolando, Ranocchia, Juan Jesus and Andreolli. If Vidic is coming for free, that’s fine. He fills the gap of experienced Samuel. Play Andreolli in full back position instead of center-back. I wish Inter signs Davide Astori, so Inter’s central defenders should be like this: Ranocchia, Rolando, Juan, Astori, Campagnaro, Vidic. If a new coach arrives and uses 4 defenders, Rano will do well for sure. Actually WM destroys many players at Inter including Ranocchia, Belfodil, Kovacic, Icardi… We need different coach!
Campa, Vidic and Juan would be great for us next season, Andreolli, Rolando and a new young def as subs
Vidic and Marcos Rojo In
Rano has been a huge disappointment. I can’t believe we gave up Bonucci, then took Rano from Bari instead of Bonucci.
I prefer Andreolli much more than Ranocchia, too bad Inter put him aside once again.. Still his love for Inter remains true.
Trust me, Bonucci isn’t all that good at all without Barzagli and Chiellini at his side.
I still believe in rano, I prefer to let him go on loan than permanent transfer
Samuel and Chivu our tripleta legends go to history and Ranocchia is one off the worst defenders who plays for Inter in history, and I’am very happy that he leave’s Inter…Welcome Vidic…
Keep Rolando, and Andreolli. Ranocchia should leave. Bring in Vidic and bring in a young defender like Schar or somebody that is a good young talent.
