'I believe Cole's best is yet to come,' says Ancelotti

London, Sep 3 (ANI): Chelsea manager Carlo Ancelotti has expressed delight over Ashley Cole decision to stay back at Stamford Bridge and believes that his best is yet to come.

Cole has signed a new four-year contract, which will tie him with the Blues until 2013.

"I am very happy that Ashley has committed himself to Chelsea. He is one of the best left-backs in the world, but I believe his best is yet to come," The Independent quoted Ancelotti, as saying.

"I am very pleased that will happen in a Chelsea shirt," he added.

The left-back, who has won 74 England caps, has made 135 appearances for Chelsea since joining from Arsenal in August 2006 and has since been an integral part of the team. (ANI)
