I’m a fan of Bonucci under Allegri, for Allegri made very good use of Bonucci’s strengths and set up the defense to work as a unit and minimize his individual defensive shortcomings. Bonucci was a big part of our Allegri-era success, we utilized his fantastic ball-playing and long-ball skills to break the press and relieve pressure on our, start counters, etc... and it worked well for us. He also worked well as part of a well-oiled, functioning defensive unit (plus entire team really) where the pieces worked together to make the sum add up to more than the individual parts perhaps.
But with Pirlo, it seems he’s instructed our defense to exclusively play the ball out from the back on the ground. No long balls, no sending it over the top to our forwards. Add to that, our defense is often left to defend alone, without much support from midfield, etc, often even as individuals and while this is harder on all defenders it is especially not something Bonucci will ever thrive at. So at this point I don’t really get the point of using him, as we are playing directly to his weaknesses. If this is the case, I’d much rather get our De Ligt-Demiral pairing off the ground and running.
