Chelsea captain John Terry, 36, will leave the club at the end of the season, the Premier League leaders announced on Monday.
Terry has hardly featured in Diego Conte's side this season, with the Italian favouring a back three of David Luiz, Cesar Azpilicueta and Gary Cahill.
"Everybody at Stamford Bridge would like to express our enormous gratitude to John and wish him the very best of luck for the future," Chelsea wrote on their official website.
"John has given us more than two decades of dedicated and exceptional service. In that time he has displayed the utmost pride at wearing the Chelsea shirt, something he has done on 713 occasions since his debut in 1998, scoring 66 goals. He is the club’s third highest all-time appearance-maker and has captained Chelsea a record 578 times.
"This season he has featured less on the field but remained an influential and inspirational member of the squad which, under Antonio Conte’s guidance, sits top of the Premier League.
"Throughout his career ‘JT’ has contributed immensely to us achieving consistent success unequalled in the club’s history. He has won the Champions League, four Premier League titles, the Europa League, five FA Cups and three League Cups. His 14 major honours make him our most decorated individual of all time."
Terry said: "After 22 years there is so much to say and so many people to thank at this great football club. From coaches, team-mates and staff to the fans who have given me so much support down the years, I can’t thank you enough. There will be opportunities for me to speak further about this over the coming weeks.
"I will decide on my future in due course, but for now I am committed to helping the team achieve success this season.
"The club and I have always had a fantastic relationship, which will continue beyond my playing days. We had some really positive talks but with everything taken into careful consideration I have decided it's the right time for me to leave. I’ve always been conscious that I depart at the right time, in the right way, and I feel that the end of this season is the right time for the club and I.
"I feel I still have plenty to offer on the pitch but understand that opportunities here at Chelsea will be limited for me. I’m eager to carry on playing and so will be looking to continue with a new challenge. I will of course always be a Blue and am desperate to end my final season as a Chelsea player with more silverware.
"Finally, words cannot describe the love I have for our football club and our amazing Chelsea fans. I would like to thank each and every one of you from the bottom of my heart for the unbelievable support you've shown me over the years. You mean the world to me and every trophy we've won during my time at the club we've won together. I will never forget the incredible journey we've been on. Thank you so much for everything."
