I think Caudrado in such a role is worth a try. Camoranesi and Zambrotta before him played similar roles in the past. Granted the latter two were more suited for the role.
Zambrotta usually played a wing back with a winger or sided midfielder his secondary position but as a true CM I dont really remember him playing..
Camoranesi is a different type of player as he is less about speed and more about control and creativity - Camoranesi is one of my all time favorites
Cuadrado is more about speed and dribblings which are more required for a winger than a CM. Also Cuadrado will get lots of cards if we are to play him there...
The truth is with Vidal we lost some defensive abilities that are less seen on the eye more on results... Its not the end of the world losing Vidal and Pirlo as we have Marchisio who can take the Vidal type of duty and we could sign a creative player to play the Pirlo type of duty (not necessarily same positions)
Also we do not have a great FK taker with Pirlo and Tevez gone...
Also noticed Pogba is a very poor corner taker
