Ashley Cole has no doubts fellow left-back Ryan Bertrand can make it at Chelsea.

Cole's consistency is what makes the 30-year-old stand head and shoulders above most other full-backs, even at the top of the game, but he too recognises a bright future for Bertrand.

"I see Ryan day in day out at Cobham and he always looks completely at home in the first team," says the former Arsenal man to chelseaf.com. "He hasn't had that many chances to show himself at Chelsea, but the loan experience he has picked up is priceless.

"I only had a few games at Crystal Palace as a loan player when I was 18, 19, and he has nearly 200 so that will prepare him well for when he becomes a regular here, and he definitely has the quality to do it."
