Ashley Cole (2006/2014)

Cole was given the number 3 shirt at Chelsea, and made his first appearance for the club as a substitute for Wayne Bridge in their 2–1 win over Charlton Athletic on 9 September.

After starting Chelsea’s first six games in the league, Cole scored his third, fourth and fifth Chelsea goals at home to Burnley, Tottenham Hotspur and Sunderland respectively. On 2 September 2009, he signed a new four-year deal which will contract him to Chelsea until 2013.

During the 2013/14 season, Cole was dropped from the Chelsea team, with César Azpilicueta replacing him as the club’s first choice left-back in the month of November. Cole captained the team on the last match day against Cardiff City in a 2-1 away win which turned out to be his last in a Chelsea shirt. On 23 May 2014, after the end of the season, he was included on the list of players released by Chelsea. Cole’s contract expired on 30 June 2014. – Wikipedia

On 23 May 2014, Lampard was included on the list of players released by Chelsea.

John Terry (1998/2017)

John Terry made his Chelsea debut on 28 October 1998 as a late substitute in a League Cup tie with Aston Villa; his first start came later that season in an FA Cup third-round match, a 2–0 win over Oldham Athletic.

Terry began to establish himself in the Chelsea first team from the 2000–01 season. On 5 December 2001, he captained Chelsea for the first time, in a League match against Charlton Athletic.

On 17 April, he announced that he would be leaving Chelsea at the end of the 2016–17 season. After Chelsea celebrated their Premier League victory, Terry played his 717th and final match for Chelsea on 21 May in a 5–1 home win over Sunderland, coming off in the 28th minute (the substitution board went up in the 26th minute, the same as that of his shirt number), and received a guard of honour from his teammates.
