Ashley Cole is the most capped left-back in England history. His club form hasn't been great this season, though and he sometimes finds himself as Chelsea's second-choice left-back.
The question is then, do England stick with the veteran as first choice or do they give Leighton Baines the nod?
Baines' offensive threat far surpasses Cole's but in defence Cole is more reliable. Perhaps the best solution would be to push Baines further up the field. He basically plays left wing for Everton anyway.
