Carl Fletcher has been sacked as manager of Leyton Orient after just 29 days in charge.
The 39-year-old, who had signed a two-year contract at Brisbane Road, failed to win any of his five matches and leaves the O’s 16th in Sky Bet League Two.
Orient chairman Nigel Travis said: “It’s unfortunate for the club that we have parted company with Carl after such a short time, particularly as we are a club that tries to preserve stability.
“However, we felt this was in the best interests of all parties and we thank him for his hard work and wish him every success in the future.”
Director of football Martin Ling told the club’s Twitter account: “I’m disappointed that we’ve had to make this decision.
“The integrity of Carl and him as a person was spot on. It just didn’t fit.
“Sometimes you can run with it and stick with it and then make a decision later on, but I feel sometimes when you make these types of decisions and you make them quickly, you get less pain.
“The fit just didn’t feel right. It sounds stupid but sometimes you go out and buy a pair of shoes and they just don’t feel quite right. It never had the feel that I thought could take us forward.”
Ling revealed Embleton has a straightforward remit for the coming days.
“Ross is going to come in and do a very, very solid job,” he added. “He was doing that before Carl came in and it’s come back on Ross.
“The word ‘interim’ means it can be as short or as long as you want.
“The be-all and end-all is I want the buzz, I want the feelgood factor back into the football club and Ross’s job, starting from tomorrow, is to get that back.”
