Centre-backs - John Terry (Free agent) and Nathan Ake (Bournemouth)
The former Blues captain represented the club in 717 games scoring 67 goals between 1998 and 2017. This places him third in the club’s all-time appearance list.
Terry won 16 honours with Chelsea during his long stint with the club and he won every possible domestic honour while he was there. In 2017, he decided to leave Chelsea up on the expiry of his contract and he dropped down a division to help Aston Villa gain promotion to the Premier League.
The 37-year-old left Aston Villa at the end of the 2017/18 season after they failed to gain promotion. Terry, however, hasn’t retired nor has he joined a new club.
Nathan Ake is another player who joined Chelsea at a very young age before going on loan multiple times and eventually leaving the club on a permanent deal.
The Dutchman joined the Chelsea youth system in 2011 aged 16 and made his first team debut aged 17 in December 2012.
Ake went on loan to Reading, Watford and Bournemouth during his stint with Chelsea. He made 17 appearances for the Blues, won the Europa League and League Cup, and was also named the Chelsea Young Player of the Year in 2012/13.
The 23-year-old left Chelsea in 2017 to join Bournemouth on a permanent deal and he has been a crucial member of the Cherries backline since.
Honourable mention - Jeffrey Bruma (Wolfsburg)
