Port Vale have parted company with former Farsley Celtic manager Lee Sinnott, who had spent less than 12 months in the job.
Saturday's 4-1 home defeat to Macclesfield Town was the third loss at Vale Park already this season and left the club 16th in the League Two table.
A brief statement on the club's official website read: "It is with regret that the club announce that manager Lee Sinnott has been relieved of his duties at Vale Park with immediate effect."
Sinnott had earlier admitted that his job was on the line, telling The Sentinel: "I'm the manager of this club until otherwise informed, and I'll do it to the best of my ability.
"The bottom line, though, is that results aren't good enough at the moment. You can't run away from that and I'm not expecting to.
"I believe I'm a bloody good manager. It's been a tough 11 months, I'm not denying that. I've learned a hell of a lot.
"I've fought long and hard to get a position like this. People above me will decide whether I stay, but I've no intention of walking away."
Sinnott replaced Martin Foyle in the Vale Park hot-seat in November 2007 but was unable to stop the club being relegated from League One last term.
