#3 Leonardo Bonucci (Juventus)
Leonardo Bonucci is one of those defenders, who has only gotten better with age. The 31-year-old Italian, who left Juventus for a short stint with AC Milan last season, returned to the Italian champions at the start of the season and has been splendid for them.
His strong partnership with fellow Italy defender Giorgio Chiellini has only helped Juventus to have a strong defensive core for the past decade or so, which has seen many legendary European teams visit the Turin club, and leave empty-handed as they were unable to breach the Bonucci-Chiellini defensive partnership.
Bonucci's aggression is one of his biggest attributes which separates him from the other top defenders. It is always intimidating to play against an aggressive defender who is stern on not letting anyone go past him.
Although he is not getting any younger, Bonucci has been consistently performing for Juventus and doesn't look like stopping for many more seasons to come.
