Perisic, Cerci, Adnan, Giaccherini...

Cerci A--->C
Giaccherini C--->A
Rizzo C--->A
Adnan C---->D

and then, it's quite uncertain:
Perisic C--->A or conversely Biabiany A---->C (It's difficult whether to consider them as wings in a 4-4-2, or external attackers in a 4-2-3-1 given the fluent dynamic of Inter's tactics, but at least they have to be put in the same role, no matter which one).

Finally I still think that Vazquez plays much more as a 10 rather than an attacker. I'd consider him still a C, so

Vazquez A---> C
