The Real Madrid has been linked with a return to the Blues for next season.
Cech said: “I have been here a long time and nothing surprises me any more.
“We had fantastic success with Jose as our manager, so why not? He is a terrific manager.
“He did a fantastic job for the club and people loved him so he deserves to have the fans singing his name.
“It’s the same for Robbie Di Matteo. If you win the Champions League it’s right that the fans should pay their respects.
“I just hope that whoever takes the job in the end will have better luck and stay for a while.
“But I’ve been saying that for the last six years."
