Why i sacked tuchel chelsea owner

I think there may be some confusion here!

Thomas Tuchel is still the current manager of Chelsea FC, and he has not been sacked by the club's owner, Todd Boehly. In fact, Tuchel has been in charge of the team since January 2021 and has led them to several notable successes, including winning the UEFA Champions League and the UEFA Super Cup.

If you're thinking of a different manager who was sacked by Chelsea's owner, it might be Frank Lampard, who was the club's manager from July 2019 to January 2021. Lampard was sacked by Chelsea's then-owner, Roman Abramovich, after a poor run of results in the 2020-21 season.

If you have any more information or context about the question, I'd be happy to help clarify things!
