Hate to say it, we might need to forgo the attacker we all want. Go all in for 2 CM's with a good injury record, a CB and a RB. Leave the attack alone.
Which would be fine because our group of strikers, left as it is, is a formidable attack. Consider Morata and Dybala's age, they're bound to be two of the best around within the next two years. Add the reliability and experience of Mandzukic and a very reliable Zaza (who can also improve). A new striker should be Marotta's lowest priority. Unless of course Morata needs replacing.
The money should go to a top midfielder and a center half and/or right back. The big question mark is what will happen with Cuadrado and Berardi. Will Cuadrado stay? Will we bring in Berardi? Will Allegri have both to choose from and if so, who plays where, when? As big a talent as Berardi is, it's hard to picture him fitting in this team as a well as Cuadrado does, remembering that Cuadrado can play as a RWB while Berardi won't be needed as a striker.
