It's not entirely true we need both. I know it'll be an unpopular opinion here but actually Berardi could be our AM exactly the way Pereyra is/was. Stretching the game by dropping to wings when needed as well as getting into opponents box is what Berardi can do. In fact he's very clinical in from of goal (much, much more than Pereyra) and he's got an eye for through balls. Good crossing also.
It all depends on what Allegri and our management think. IMO it'd be better to get Berardi early so he'd train with the squad from the very first day instead of chasing Gotzes and Iscos just to end up with a panic buy like Hernanes.
This Summer some crazy spending is going to happen, that's for sure. We better give Allegri all new pieces he needs early so we won't face another slow start.
I guess Vrsalijko will be bought too but on the other hand I very doubt we'll buy out Cuadrado. It seems we don't consider the 20m a good price and in the end Conte will block the move anyway xD
BTW. Another option for AM that should be treated seriously is Saponara, just saying
