The former goalkeeper will become the latest to leave the club following Todd Boehly’s takeover following the departures of chairman Bruce Buck and director Marina Granovskaia last week.
Cech, who returned to Chelsea in June 2019 after announcing his retirement from playing told the club’s website:
It has been a huge privilege to perform this role at Chelsea for the past three years. With the club under new ownership, I feel now is the right time for me to step aside. I am pleased that the club is now in an excellent position with the new owners, and I am confident of its future success both on and off the pitch.
Boehly, chairman and co-controlling owner, added:
Petr is an important member of the Chelsea family. We understand his decision to step away and thank him for his contributions as an advisor and his commitment to the club and to our community. We wish him the best.
A report in The Telegraph has claimed that Boehly had wanted Cech to assist him during the current transfer window, like Granovskaia will continue to do until the end of August.
However, Cech has opted to make a clean break from a club where he will be regarded as a success in his roles both on and off the pitch.
As well as making 494 appearances for Chelsea during his playing career, the 40-year-old has recently been instrumental behind the scenes when it has come to signing new players.
Cech formed part of an exciting rebuild at Chelsea under the guidance of Jose Mourinho, and was the club’s No.1 for 10 years before eventually slipping behind Thibaut Courtois in the pecking order, making 494 appearances for the club in total.
