Blues fans were left baffled when technical and performance advisor Cech, who won four Premier League titles and the Champions League in 11 years as a goalkeeper at Stamford Bridge, was named in their 25-man squad for the 2020/21 campaign.
The legendary shot-stopper retired after finishing the 2018/19 season with Arsenal, before returning to Chelsea in a technical capacity last year to assist former team-mate Lampard.
However, after training alongside current goalkeepers Edouard Mendy and Kepa Arrizabalaga at Cobham, Cech is ready to return in goal if required.
“It’s true that it would have been a professional error to do this if I wasn’t at Premier League level, but that’s not the way we work here,” he told Telefoot.
“I know I’m 100 per cent ready to help if needs be. I’m fit, and with the two months of training, I’ve seen I have the same quality.
“Furthermore, I rested for a year without playing football. It really gave me energy, my body recovered after playing 20 years as a professional.
“If the circumstances put me on the pitch, I’m ready.”
With the coronavirus pandemic still proving a threat to player fitness, Cech may be required to at least sit on the bench at some point this season.
He certainly won’t be needed for any other reason in the near future, as new signing Mendy has got off to a flyer since joining Chelsea in the summer transfer window.
The Senegalese shot-stopper has kept a clean sheet in each of his first three Premier League appearances, inspiring a newfound defensive stability for Lampard’s side along with new centre-back Thiago Silva.

Blues defender Kurt Zouma has been impressed by Mendy, telling the Standard: “He has been great, with the ball at his feet and he is big, too.
“He has presence and catches the ball when he comes out. He is talking a lot, doing a great job. He settled in very quickly, but we have to keep focused.”
