Chief Executive Chris Jurasek has left Chelsea and will be replaced by Jason Gannon, the Premier League club said on Thursday.
Jurasek will return to Clearlake Capital, the co-controlling owners of Chelsea, after just over a year in the role at the club.
"I am incredibly proud to have led this historic football club into its next chapter," Jurasek said.
"We have accomplished the task of building a team both on and off the pitch that means the club is well-positioned for long-term success."
During his time as chief executive, Jurasek made several decisions that were met with disapproval by Chelsea's match-going supporters, including referring to them as customers rather than fans.
He also ended a long-standing bus subsidy for away fans and implemented the first general admission season ticket price increases in over a decade.
