IMO Berardi is a very direct, shoot first-think later player who relies a lot on instinct. For all the talk Allegri gives about freedom in the final third, imo he's not a fan of these types of players (Berna used to have a similar approach and was getting comments like "this is not Fiorentina" from Allegri) and Max prefers smarter, more calculated players or, as Allegri would put it, players who play with "serenity"
