There will be a couple instances where he's beaten for pace but I think he's a disaster when he's sitting deep trying to mark headers. He's never been a man marker. The way Sarri plays, the CBs just hold the line and watch the ball. I think Bonucci is better like this, I don't know if he will be better than Demiral though, who looks like a monster.
Under Sarri's system hopefully Bonucci offensive contributions will outweigh his defensive miscues. Of course I guess was dreaming of 100 league goals last season but thought a reality of more often having a 2-0, 3-1 lead at the 75-80 minute mark instead of 1-0 with CR7 would happen. This year the safe lead must happen!
