I think that is the original plan, Danilo plays on the right because Sandro is out, with Alex there the left wingback would be an attacking player and Bernardeschi is one of the options, Cuadrado as a RWB and both ASandro and Cuadrado the FBs when team needs to defend with 4 at the back, Berna/Chiesa/Kulusevski the wingers...
So far Danilo has been good, Pirlo has a lot to think about, we need more games to see how several players can be used in most efficient manner.
