Notts County have sacked manager Jamie Fullarton after Saturday’s 4-1 defeat at home to Exeter City.
Owner Ray Trew, who is in the process of selling the club, said the decision had been made after a run of seven games without a win.
The league two club said recent form had led to fears the club could end up sucked into a relegation battle.
Mr Trew said in a satement: “Whilst it is well-known that my position at the club has changed in recent weeks, I still have a responsibility to do what I feel is best for Notts County and that means acting when things aren’t going right on the pitch.
“I have to thank Jamie for his efforts over the past few weeks because he has had to face an incredibly difficult atmosphere, somewhat unfairly I feel, but has maintained an exceptional level of professionalism throughout and should be applauded for how he has conducted himself.
“There is no doubt in my mind that Jamie still has a very bright future in the game, but I acknowledge that what was already a tough challenge for him here at Meadow Lane was made all the more difficult through a number of factors that were beyond his control,” he added.
“We understand fans fears and frustrations, and the most important thing for Notts County is that this season does not dissolve into a disaster and a level of stability can be brought in to ensure that there is a strong platform to build from for the new owners, once a deal is completed to sell the club.”
Fullarton took charge in January after being appointed to replace Ricardo Moniz.
