#2 Leonardo Bonucci
Possibly the best defender in the world right now, Leonardo Bonucci, is second on thie list only because he's isn't the best ball-playing defender on this list or out on the field. The Italian is one of the reasons Juventus have been able to win the Serie A five times in a row.
His leadership qualities and last-ditch tackling has won the game for the Turin club multiple amount of games. While he's 28-years-old and a huge target for Chelsea given the arrival of Antonio Conte, maybe the chance to play at the Camp Nou with Barcelona could turn his head.
Bonucci is the kind of defender Pique would love playing alongside. He's as defensive as defensive can get and will often tolerate Pique's runs into the middle of the park. His physical strength and sharpness will allow him to read the situation and deal with it better than most defenders can.
