John Sheridan returned as manager of Oldham Athletic in January 2017 for the third time.
A midfielder by trade, Sheridan had an illustrious playing career before turning his hand to management.
He played 230 games for Leeds United and scored 47 goals in a seven-year spell before briefly joining Nottingham Forest under Brian Clough.
Sheridan went on to join Sheffield Wednesday and made just under 200 appearances for the Owls between 1989 and 1996.
He scored the winning goal for Sheffield Wednesday in the 1991 League Cup final against Manchester United which saw him become a legend at Hillsborough.
During his time there, he also represented the Republic of Ireland at international level and went on to gain 34 caps. That included appearances at two World Cup's in 1990 and 1994.
Spells at Birmingham City, Bolton Wanderers and Doncaster Rovers followed before Sheridan joined Oldham Athletic as a player in 1998.
Sheridan would have two spells as caretaker manager of the club in his six-year spell with the club, in 2001 and 2002/03 as Iain Dowie departed the club for Crystal Palace.
He decided to hang up his boots in 2004, a couple of months short of his 40th birthday.
Sheridan would be back at Boundary Park in the summer of 2006 as he was appointed as the club's permanent manager, replacing Ronnie Moore.
He made an immediate impact and won the hearts of Oldham Athletic supporters as in his first season he guided the club to the League One play offs but was beaten in the semi-finals by eventual winners Blackpool.
An eighth-placed finish followed the next season but Sheridan was sacked by the club in 2009 following a poor set of results and he was replaced by former manager an Oldham Athletic legend Joe Royle.
Sheridan was not out of the game for long and was appointed manager of Chesterfield in the summer of 2009.
He won the League Two championship in his second season in charge before lifting the Johnstone's Paint Trophy the following season.
Spells at Plymouth Argyle and Newport County followed as he helped both club's stay in the Football League, but Oldham Athletic came calling for his services once again in January 2016.
Latics found themselves in the relegation places but Sheridan turned the club's fortunes around and kept the club in Sky Bet League One for their 20th consecutive season.
At the end of the season, Sheridan opted to join Notts County but he suffered a turbulent spell with the Magpies and returned to Oldham Athletic in January 2017, a year to the day since he joined the second time.
Sheridan inherited a squad at the bottom of Sky Bet League One but again guided the club to safety with a game to spare.
