Former Ireland international John Sheridan has left his position as Oldham manager after a shocking start to the League One campaign.
The Latics sit at the foot of the table after losing seven of their opening nine games, the latest defeat coming in the form of a 5-1 hammering at Rotherham on Saturday.
Sheridan, who was in his third spell in charge at Boundary Park, said after the loss at Rotherham that he expected his position to come under scrutiny and he exits by mutual consent.
A statement on the club's official website read: "Oldham Athletic (2004) AFC Limited can confirm that first-team manager, John Sheridan, has left the club by mutual consent.
"The board of directors would like to place on record their thanks to John for his contribution to the development of the club, not only during this tenure, but as both a player and manager previously.
"His impact over the past two seasons in particular, when he has saved the club from near certain relegation on both occasions, will mean he is always guaranteed a warm welcome here by both the club and fans alike.
"This season, however, has not seen the progression we hoped with what was felt to be the nucleus of a good squad, and results, performances and league position have been hugely disappointing.
"Therefore following discussions with John, this decision has been made in the best interests of the club. We wish John well for the future."
