People that say Zaniolo is redundant, or that Moggi post about him not fitting because he is a player who shoots and not one who serves, have you forgotten how difficult it is for our team to score currently?
We have an extremely low goal contribution from midfield. Locatelli is our most credible threat but he plays in front of the defense. Our fullbacks basically do not score, Alex and Danilo are defensive fullbacks. Cuadrado can contribute to scoring, as a defender or attacker, but Cuadrado is like 35, as is Di Maria.
We have a dearth of goal scorers and players who create chances. Chiesa does both things but again he is coming from a big injury. The other two wingers have 70 years old combined, they cannot play every minute.
Players like Pogba and Zaniolo that can create chances and finish them are needed. If Valhovic is our only scorer we risk to centralize most defenders attention on him.
We do need attackers.
