Chelsea have fired head coach Thomas Tuchel only one month into the season.
The decision by Chelsea's new ownership after last night's loss to Dinamo Zagreb 1-0 in its first group match in the Champions League.
Chelsea has lost two of its first six games in the Premier League.
"On behalf of everyone at Chelsea FC, the club would like to place on record its gratitude to Thomas and his staff for all their efforts during their time with the club," Chelsea said in a statement.
Chelsea was the highest-spending team in Europe during the transfer window with an outlay of nearly $300 million.
Tuchel was in charge for a year and a half, winning the Champions League in his first season.
