It is hard to think of a position where the roles and responsibilities have changed more over the last 30 years than full back.
They have always been important and my ex-Arsenal team-mate Ashley Cole is one of the best attacking full backs seen in the Premier League. But now we have an array of top players in this position and it is astonishing to see.
Today’s full backs and wing-backs are some of the most talented footballers at a club. They are so technically gifted that they could easily play in midfield — and Chelsea’s Reece James did that with an accomplished display against Zenit St Petersburg in the Champions League.
