Giacch is just like Pepe, but not that good. If we play 4-3-3 I can see him starting. Maybe not vs Udinese. Depends if Conte decides to play 4-3-3 or 3-5-2. I'm all for 4-3-3 but yeah, unlikely.
Quag playing? That would mean that the goals will come from either one of Giovinco, Vucinic, Pogba, Vidal, Barzagli, Bonucci, Lichtstiener De Cegile, Pirlo or Buffon.
