Petr Cech has stepped down from his role as technical and performance advisor at Chelsea.
Cech is the latest to leave the club following the Todd Boehly-Clearlake takeover after the departures of chairman Bruce Buck and director Marina Granovskaia.
Co-controlling owner Boehly was named chairman and interim sporting director last week.
As acting sporting director, it is understood Boehly has been hands-on in the role already, playing a key part in the decision to let Romelu Lukaku rejoin Inter Milan on loan.
Cech said: “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 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.”
