#3 Cesar Azpilicueta - Chelsea
If David Luiz was the legs and Gary Cahill was the heart of Chelsea's back three, Cesar Azpilicueta was the brains of the title winning side. The Spaniard has been a utility player all his career and gave a fantastic account of himself in Chelsea's run to the Premier League title. With 2.2 tackles and 3.1 clearances per game for the Blues, Azpilicueta displayed his authority in an alien position for him.
It is safe to say that Antonio Conte's three at the back system became a roaring success because he had a player like Azpilicueta at his disposal. He did his reputation of being the best one v one defender no harm whatsoever. The Spanish defender tackled well and also chipped in with a few goals and assists. All in all, Azpilicueta was the Premier League's best defender of the 2016/17 season.
