Full-backs have become one of the most important components of a team - as they now have to defend and attack.
Gone are the days when a full-back was deployed in a side to simply stop an opposing winger from causing damage to their team.
The Premier League currently possesses several top quality full-backs, with the likes of Patrice Evra, Ashley Cole and Leighton Baines all outstanding footballers when on form.

Here we rank the Premier League's best full-backs.
