#1 Leonardo Bonucci
After a successful spell with Juventus, Bonucci secured a shocking move to AC Milan in 2017 even though some big clubs were looking for the defender.
The Italian regretted the decision within a few months after the club's terrible run of form. Bonucci is clearly among the top three centre-backs in the game at present.
The 30-year-old is eyeing an exit from San Siro in the upcoming transfer window. The defender would certainly find takers given his abilities. In 2017/18, the defender has an average duel winning rate of 48% and took six defensive actions per game, domestically.
Real Madrid have already been reported plotting a move for the player in the summer.
The player has at least three more years lying in front of him. Los Blancos should not let an opportunity to sign such a player let go off easily.
