What if we get a new manager who doesn't believe at all in Molinaro and would use Criscito and DC for the LB position?
And as you claim, Molinaro is Ranieri's favourite player, don't you think if Ranieri leaves he will take Molinaro with him?
I think it's way to early to speculate anything as we don't know who will lead the club next season.
That assumes that Ranieri will remain in football management. This post at Juve could well be his last.
Cronios is right in re-emphasizing the need to concentrate our resources in the defensive full back positions, I'm pretty much certain that in order to strenthen our right side that our primary focus shoule be on signing Lorenzo De Silvestri.
De Silvestri plays as an attacking right back. His pace is useful for his attacking runs up the wing, and possibly his greatest attribute. Since making his debut, De Silvestri has continued to improve the technical and tactical aspects of his game under the guidance of manager Delio Rossi, and is becoming a very valuable player. He is widely regarded as one of the most promising talents of his generation.
Maldini has rated Domenico Criscito very highly and his continuing improvement at Genoa this season makes his return to Turin a no-brainer. Looked at against Molinaro he is undoubtedly a better player. No fee is involved so in selling Jonathan Zebina or Zdeněk Grygera and Dario Knežević this should help towards financing a left sided attacker.
Whilst David Silva is commonly thought to be an obvious target, I'm afraid that Rafael Benitez at Liverpool in one last desperate throw of the dice - now that Manchester United have all but won yet another EPL title - will persaude the Liverpool owners to splash the cash for Silva and given the fact that there are more Spaniards than English players at the club the Valencia player would probably opt to play there.
So the question is who would fit the bill as an alternative to David Silva?
Assuming we persist with Mauro Camoranesi, the starting XI may well look like this:-
---------------------------------- BUFFON------------------------------
--DE SILVESTRI----CANNAVARO ---- CHIELLINI----CRISCITO---
-----------SISSOKO-----------------------MARCHISIO---------------
CAMORANESI--------------------DIEGO-----------------------------
-------------------------AMAURI/IAQUINTA------------------- ???????????-----
So the position looks rocky for Sebastain Giovinco, Alessandro Del Piero, Marco Marchionni, Hasan Salihamidžić, Christian Poulsen and those I've mentioned above.
Iaquinta will surely be knocking on the door for a starting place. David Trezeguet will almost certainly be leaving and the sale proceeds will go towards the Silva/left-sided starter.
The best prospects for the bench would be:-
Alex Manninger, Olof Mellberg, Nicola Legrottalie, Tiago, Alessandro Del Piero, Sebastian Giovinco, Zdeněk Grygera and Albin Ekdal.
