Matuidi, Khedira and Pjanic was like 10 times better midfield than what we have. A tireless runner, an intelligent player who could always find spaces and a playmaker. Those three were rarely losing the midfield. They had their flaws, but wherever they played (PSG, Real, France, Germany etc.) they were sure starters and important parts of a functioning midfield. It wasn't just Allegri that made them play.
Of course, it's an insult to even compare Allegri and Pirlo as coaches, but we're also talking about inferior quality that we have in our team right now.
