The official Blues website marked Cole's departure with a lengthy farewell message and a swipe at his former club:
"Chelsea Football Club today says goodbye to Ashley Cole, a player who contributed enormously to the highly successfully period in our history in which we were crowned champions of Europe and won the League and Cup double for the first time.
"His remarkably consistent high level of performance was always appreciated by the Chelsea support, who welcomed him to Stamford Bridge even though he joined from big London rivals Arsenal, with William Gallas moving the other way as part of a transfer-deadline-day deal in August 2006.
"Cole has had no reason to regret his switch across the capital, collecting winners' medals for the Champions League, the Premier League, the Europa League, the League Cup, the Community Shield and the FA Cup four times, taking him to his all-time record seven wins in that competition's long history.
