You could make a case for Morata + Pirlo together making a difference, Allegri said it himself if you want a striker to run the channels then it's Morata. If not, then Llorente
So assuming Llorente would've been picked anyway, adding Pirlo in to the mix wouldn't have been a significant help offensively, and defensively he'd be targeted
Hell if they done a number on Pirlo (It's very likely they would have) we'd do what we used to, and get Bonucci to step up and take over from him. Nobody wants to see that.
