Milik could be a focal point of the attack – wining longballs, playing with his back to the goal, keeping the ball, dishing it to the sides, and running for crosses, and with that creating a depth that both Dybala and CR can use. Atm, there is no one to keep central defenders honest. If CR is in the middle – CBs play him 2 to 1 and he is shut. If he is on a side – they play a bit higher, closer to midfield and there is no place for CR and Dybala to operate. At least this can be the case for 433, and it's up to Pirlo to make this work and not to get overrun.
