Sunderland have chosen to sack manager Phil Parkinson after a year in the job.
The 52-year-old came to the club in October 2019 with high hopes.
He helped the team finish eighth in League One last season.
They are in the same position after 13 games this term, but the lack of progression means the club felt it was best to make a change.
Fans were not happy with the turgid football under Parkinson's tutelage either.
A statement from Sunderland said: "The club would like to place on record its thanks to both Phil and Steve for their efforts during their time at SAFC.
"The board will now begin the search for a new manager and will make no further comment until this process is completed."
