As a former left-back of some repute himself, Nottingham Forest legend Pearce has no hesitation delivering the ultimate accolade.
"I have never been a great lover of trawling through the media for personal stories about people. My interest is football and Ashley Cole is the best left-back that has ever represented England by a million miles," said Pearce.
"Arguably he is the best in the world at present and for us to lose him for the summer would be a big blow.
"He doesn't carry a lot of weight so we hope the injury heals early enough for him to get some form and fitness ahead of the World Cup."
