Speaking to Chelsea's club media, Ingle said: "Chelsea is a special club and since I returned seven years ago, I have felt the support of everyone, both on and off the pitch.
"I’m very proud to have lifted 11 trophies here and am grateful to have done that alongside team-mates who are like family to me.
"We have achieved so much together, but couldn’t have done that without the fans, who I want to thank for always being there with us throughout the journey."
