Very good post Mike
Currently, giovinco is supposed to be our "counterattack" specialist, but only did so against chelsea at home efficiently.
Now while sanchez is good at it, i'm still reservated cause the other mentionned SS are good at possession, and to a bit lesser extend then sanchez ,are also good on the counterattack.
The reason Sanchez could work is indeed the counter, but the added value of llorente.
I think it was red who noticed Llorento to a) act like a targetman as vucinic but much deeper, weight on defence and a threat, and b) because of that its good to pair him with a mobile ss
Now the space between mid and attack, if conte can get Sanchez to use the space that Llorente creates, with marchisio or vidal following behind that, it could be very potent indeed, and pretty hard to defend against.
Like for example Napoli using Cavani's target capabilities, and players like hamsik using the space he creates effectively
Most important is wether conte thinks he can pull this off, but iirc he liked sanchez very much and wanted him here in the first place
